JavaScript - How To Manipulate A String Into Alot Of Smaller Strings.
Thanks again for answering my questions perfectly previously, this next one really tested my minimal coding knowledge, and bested me. Basically, what I need done is this:
This is a form [This is a text Box] [This is a submit button] Users on my website will enter a URL into the text box and press submit. Upon pressing submit it will redirect them to a webpage based on what they inserted into the textbox, sounds easy. But this is where it gets complicated. I need to take out certain parts of the URL they entered and place them inside of another URL. Here is an example www.google.com/images/picture/Download77_75.html I need to take the words in BOLD and Itallics and insert them specifically into another URL. which they will be redirected to after pressing submit. so now redirect to www.Mywebsite.com/Download77-with/GIF/images Basically I have the original string, which like above would be www.Mywebsite.com/Italicized string-with/GIF/Bolded String The original redirect link would stay the same. And taking from what you entered into the form, it would take out the specific bits and add them into the specific bits into another URL and redirect to that URL. Please note that I believe this is only possible becuase the amount of characters between the strings will ALWAYS be the same based on the content that my users are putting into the submit box. I.E the string in the Italicized string will always be 10 characters long, and everything in the Bolded String will always be 8 characters long (Not really, just an example). So maybe the script could tell it to count characters and take out characters from characters 8-15 and characters 19-36 then place them in the specific spots and then redirect them to that compiled link. Thanks for ALL the help! This one really boggled my mind. I could not think of anything that would help. This forum has come out to be my BEST resource %100 of the time. If you could help me with this. I will be AMAZED. Thanks in advance! PS: It doesen't have to be in any particular code language, But I do prefer HTML and Javascript. Similar TutorialsI am now working on a utility function that will gather the indexes for substring matches found in a string. There is an academic mystery I am puzzling over Code: function getMatchIndex(a, b) // a: sting to search b: what to search for
{
var out = new Array();
if(a.lastIndexOf(b) > -1) // at least two matches, ****! there could be more
{
if( (a.substr(a.indexOf(b) + b.length, a.lastIndexOf(b))).length > b.length )
{
var stp = parseInt(a.lastIndexOf(b)) - (parseInt(a.indexOf(b)) + parseInt(b.length));
alert(stp)
alert( (a.substr(a.indexOf(b) + b.length, stp)).length+' : '+a.substr(a.indexOf(b) + b.length, stp));
}
else
{
out[out.length] = a.indexOf(b);
out[out.length] = a.lastIndexOf(b);
return out;
}
}
else if(a.indexOf(b) > - 1 && a.lastIndexOf(b) == -1)
{
out[out.length] = a.indexOf(b);
return out;
}
else if(a.indexOf(b) == -1)
{
out = 'no matches';
return out;
}
else
{
var splitStr = new Array();
splitStr = a.split(b);
/*
possibilities:
1: one match at the begining or end
-- leaves one significant item
2: one match somewhere after the beginning and before the end.
-- gives two matches.
*/
for(var i = 0; i < splitStr.length - 1; i++) // don't want the last segment length
{
out[out.length] = splitStr[i].length
}
}
}
getMatchIndex('xxxi5ixxxxxxxi5ixx', 'i5i');
in the following code snippet: Code: if( (a.substr(a.indexOf(b) + b.length, a.lastIndexOf(b))).length > b.length )
{
var stp = parseInt(a.lastIndexOf(b)) - (parseInt(a.indexOf(b)) + parseInt(b.length));
alert(stp)
alert( (a.substr(a.indexOf(b) + b.length, stp)).length+' : '+a.substr(a.indexOf(b) + b.length, stp));
I am trying to get the sub string between the end of the first match to the beginning of the last match. The 'if' test passes, but I have to parseInt the values to get the proper value for stp. SO, the question is, what is the actual data type of an index value obtained from a string. (It would appear to be a string; having to use it an a math expression doesn't work without parseInt). (I hope I haven't posted too much code) Thank you in advance. Hi I have problem to manipulate my form with array. I want to copy my input from one input to other input but it didnt work. i did explore the usage of document.myForm.feed[3].value but it gave me error. Pleaseee help? Thanks script sample: <form name=myForm> <input name=feed[] onBlur=duplicate(this)> <input name=feed[] onBlur=duplicate(this)> <input name=feed[] onBlur=duplicate(this)> <input name=feed[] onBlur=duplicate(this)> <input name=feed[] onBlur=duplicate(this)> <input name=feed[] onBlur=duplicate(this)> <input name=feed[] onBlur=duplicate(this)> <input name=feed[] onBlur=duplicate(this)> <input name=copier[] onBlur=sendback(this)> <input name=copier[] onBlur=sendback(this)> <input name=copier[] onBlur=sendback(this)> <input name=copier[] onBlur=sendback(this)> <input name=copier[] onBlur=sendback(this)> <input name=copier[] onBlur=sendback(this)> <input name=copier[] onBlur=sendback(this)> <input name=copier[] onBlur=sendback(this)> <input name=copier[] onBlur=sendback(this)> </form> <SCRIPT> function duplicate(info) { //this function should copy 'info' to copier input //with the same element location //eg: feed[3] will copy to copier[3], feed[5] will copy to copier[5] //(can be any element insert by user) // the task would be: // 1. to get which element number has been inserted // 2. to get the origin text value // 3. to write the same element position for copier } function sendback(info) { //this function should copy 'info' to feed input //with the same element location //copier[2] will copy to feed[2], copier[3] will copy to feed[3] //(can be any element insert by user) } </SCRIPT> Hey peeps, I'm trying to use wget to access this website that uses javascript. The website is from my work. Basically I made a program that parses information from our payment page. It tells me how much I am being paid for the month. Anywho, the variables on the page are in javascript, and thats one language I'm not proficient at. I need to change the month that it gets the pay for. The default is the current month. But it can be changed to last month, and from the code I can tell that something has to be changed from "THIS_MONTH" to "LAST_MONTH", but I'm not sure how to properly do it. Posted below is the source code from the website. Please let me know how I can change that without actually having to click the button to change the scope to last month. And also, is there any way to change this in the post method, or any other method that wget uses? I only included the parts I thought could be relevant. Thanks guys! BTW, I think it pertains with g_FiltersMenuStr Code:

Hello. I need to manipulate with a upper and lower case on STRINGS For example I have string: Code: LALA_KAKA_mama_WIWI I need to conwert it to Code: Lala_kaka_mama_wiwi with first letter upper case. Is it one simple way to do it with JS script/code? Best Regards Hi all, I have a newbie question. I have just started working with javascript and would appreciate some guidance. I have a webpage and there are products for sale on it(this is not live it is merely being used as practice project). Beside each product is a description a price and an 'add to cart' button. My cart is simply a div with an id of 'cart' and it has a text box within it. I need the product name to be displayed within the div (this, I have working), I also need to display the product price in the text box once the button(add to cart ) for that particular product has been pressed. Also when the button for another product is pressed, I want the cost/value for that product to be added to the other value and displayed in the text box in the cart div... I apologise for rambling on but this is the best way of me explaining my needs.... Here's where i am right now.. The HTML snippet Code: <div id ="cart">
<p><img src="images/shopping-cart.png" alt ="cart"/>Your Cart</p>
<div id="sum"><!--(this is the div where the total goes)-->
<input type="text" id="total" value="0" /><p>€ Your Total <input type="reset" value = "reset" /></p>
</div>
</div>
<h2 id ="black">Blackcurrent<br /></h2>
<p>€ 12.00 <input type = "submit" value ="add to cart" onClick = "shoppingCart('Blackcurrent',12)" /></p>
And the javascript: Code: alert ("working");
function shoppingCart (itemName,itemValue)
{
/* var thePrice = Number(itemValue);
return thePrice;*/
document.getElementById ("cart").innerHTML += itemName + "<br/>";
document.getElementById('total').value = Number(document.getElementById('total').value) + itemValue;
}
I hope i have posted correctly and am aware that i have only posted a segment of the HTML.. Please let me know if you need any more code or info.. Thanks a lot in advance for any help... Any idea how can I use the slimbox to create a really small lightbox (such as 5x5 pixels), instead of the usual large lightbox? Your help is appreciated. Hello all I want to use javascript to open a small div as an enlarged one using a fade effect when doing so, anyone can pls help? refer to my attached image for what i want to do (example is when click on the small 'contact us' it opens as an enlarged div at the bottom, same for the other 2 divs) Hi: The code below, partly suggested by Old Pedant, will open the radio button PDF file, but it will take up the entire screen. Is it possible to open the checked PDF file in a slightly smaller screen so that the user, when finished with the PDF file, can always be sure that he/she is closing only the PDF file and not the browser? I'm trying to use the showDetails() to do this, but am having two problems: 1) where in the <body> should this function be "called", and 2) how does one get a file name into the first parameter of window.open when the name of the file is not known until the user has checked one of the several choices? Or is it the Foxit and Adobe Readers that govern the screen size of the PDF files, and not Javascript? Thanks for any help and pointing me in the right direction. <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Open smaller PDF window.html</title> <script type="text/javascript"> function goToCheckedValue ( rbs ) //courtesy of Old Pedant { var go = null; if (rbs.length == null ) { if (rbs.checked ) go = rbs.value; } else { for (var r = 0; r < rbs.length; ++r ) { if (rbs[r].checked ) go = rbs [r].value; } } if ( go == null ) return; location.href = go; } var detailsWindow; function showDetails() { //leave filename parameter blank detailsWindow = window.open("","", "width=500,height=350"); detailsWindow.focus(); } </script> </head> <body> <form name="myForm"> <fieldset id="pdfchoices"> <input type="radio" name="gmplitword" value="11.pdf" checked="checked" /> Gospel Acclamation <br /> <input type="radio" name="gmplitword" value="15.pdf" /> Gospel Acclamation - Lent <br /> <input type="radio" name="gmplitword" value="16.pdf" /> Gospel Acclamation - Paschal time <br /> <input type="radio" name="gmplitword" value="23.pdf" /> Apostles' Creed (IV) <br /> <br /> <input type="button" value="Open PDF file" onclick="goToCheckedValue(this.form.gmplitword)" /> </fieldset> </form> </body> </html> I am not sure if this is a javascript problem or an html problem. I have posted the code below. The main two areas that I am interested in are 1) the area where the photo is shown in the larger size, and 2) the thumbnails below the larger picture. Right now in the img tag of the first image I have specified a height and width of 450px. The result is that when one hovers the mouse over the thumbnails, all pictures are shown at that size, regardless if they are larger or smaller than 450 x 450 pixels. I am not concerned about the larger images because I will use a script to scale those that someone on this forum was so kind enough to provide me with. The IMPORTANT PART IS HE I am concerned with smaller images. If you remove the height and width portion from the image tag, when you hover the mouse over a picture that's smaller than the others, such as the last one, which is smaller than all the others that are at 450 x 450, the thumbnails "move up". I would like the thumbnails to remain where they are at / for the top area where the photos are displayed to always be the same size, such as 450 x 450 px., and for the smaller pictures to be shown in the center in that area. How can this be done? Note: The entire portion of the stylesheet is not present. Let me know if something important is missing. Code: <html>

Okay so I have this code for HMTL5 Canvas, however this is a JavaScript directed question not a Canvas question. Code: <script type="text/javascript">
var c=document.getElementById("myCanvas");
var cxt=c.getContext("2d");
cxt.moveTo(0,400);
cxt.lineTo(50,a);
cxt.lineTo(100,b);
cxt.lineTo(150,390);
cxt.lineTo(200,300);
cxt.lineTo(250,285);
cxt.lineTo(300,299);
cxt.lineTo(350,250);
cxt.lineTo(400,325);
cxt.lineTo(450,275);
cxt.lineTo(500,300;);
cxt.stroke();
</script>
That will draw a line graph, however I want to get the coordinates from a variable in the URL. So it may be example.com/a=500&b=600 . How would I retrieve these two variables and then insert in to they're respective places? Any help greatly appreciated, please make it as simple as possible - I'm good with my PHP now but JavaScript is all new How do I join strings? I tried below but get an error. var a += document.getElementById("PICKUP_TYPE").value + "~"; var a += document.getElementById("PICKUP_ADDRESS").value + "~"; var a += document.getElementById("PICKUP_ADDRESS2").value + "~"; I'm new at JavaScript and am trying to figure out a simple text calculator as seen on a science project website. The project says the final program should calculate: 1. the number of sentences contained in the text, 2. the number of words in each sentence, 3. the number of letters in each word, 4. the average number of words per sentence, and 5. the average word length. I have pretty much everything (I think) but am being completely stumped by item number 2 and item number 4. The code is below. Can anyone help me understand what I should be doing for point number 2 and 4? I understand how to calculate and display the length of an item in an array and return it's values as 5,6,7,8 etc where the value is the length of the word, but i can't grasp how to calculate the number of items in an array to read 2,5,9 where the values are the number of words per each sentence...so confused! Below is my code...apoligies if it's sloppy...it's my first javascript code experience Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Count</title> Code: Hey all, I have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function: Code: <body> <select> <option value="createMsg">Add Message</option> <option value="removeMsg">Remove Message</option> </select> </body> Code: var menu = {
handleMenu : function(callback){
if(callback === "string"){
menu[callback]();
}
else {
console.log("Issue occurred")
}
},
createMsg : function(){
var content = document.createTextNode("Please give additional information."),
heading = document.createElement("h1");
heading.appendChild(content);
document.body.appendChild(heading);
},
removeMsg : function(){
}
}
document.getElementsByTagName('select')[0].onchange = function(){ menu.handleMenu(this.value)};
callback should be a string so why is it saying otherwise? Thanks for response Hi All, I'm trying to convert a string based on the contents of another string. For example, I have two strings - "Purple" and "Orange" and a variable "P" - I want the script to look at the word "Purple" and everytime is sees the letter "P", assign this to a third variable (result variable) - if the letter it's looking at is not a "p", I want it to take that character from "Orange" and add it to the result string. So the result would be "Prapge". This is the code I have so far, and it doesn't work, absolutely stumped as to why ... Code: function fillInChar(targetString, otherString, newChar)
{
var splitTarget = targetString.split('');
var splitOther = otherString.split('');
var resultArray = newArray(splitTarget.length);
var holdVar = '';
for (var position = 0; position < splitTarget.length; position = position + 1)
{
if (splitTarget[position] != newChar)
{
var holdVar = splitOther[position];
resultArray[position] = holdVar
}
else
{
resultArray[position] = newChar
}
}
return resultArray
}
document.write('IF VISIBLE - LOOP IS VIABLE' + '<BR>')
var testVar = fillInChar('purple', 'orange', 'p');
document.write('HELLO WORLD!!! .... ' + testVar);
Hi, I know virtually nothing about js so here goes: I use the following script: Code: <script type="text/javascript">var showNav = false;var params='clubID=1784&compID=8041&leagueTable=y&orderTBCLast=Y&colour=147C99';var colour = '147C99';</script> The variable which needs to be called from another page is 'compID' - as I have about 20 competitions rather than hard-coding each page I hoped to generate this from the following: infocus/respage.php?cid=8041 <--- where I can change the compID from the 'calling' page. In my absolute naivety I thought I could simply change the code to this: Code: <script type="text/javascript">var showNav = false;var params='clubID=1784&compID=cid&leagueTable=y&orderTBCLast=Y&colour=147C99';var colour = '147C99';</script> But as the learned among you will realise this just doesnt work - any help appreciated! Hello, A quick summary to inform you on what I'm trying to accomplish and then the question. If you want to skip to the question first, I have it in red letters lower down. Just figured I'd answer the "why are you doing it this way" question first. I am writing a tool in JavaScript in which a user selects various options via checkboxes and then a pre-engineered scenario image for a product matching those selections is displayed. Here is the basic workflow of the code: 1. The code runs through the checkboxes and based on whether the boxes are checked or not, adds a value of "1" or "0" to a string. There are some dashes added into the string to visually divide some categories of options. Here is an example of the resulting string: 0-0011100-101100 2. A variable named scenarioID holds the value of the resulting string. A switch statement is run which assigns a name to the scenario based on the scenario ID. Here is an example: PHP Code: switch(scenarioID){ case "0-0011100-101100": var scenarioName="Scenario 1"; break; } 3. The scenarioName variable is then used to pull up an image with the corresponding name. For example, if the scenarioName variable has a value of "Scenario 1" then an image named "Scenario 1" is displayed. --------------------------------------------- So here is where I am running into an issue: I have some scenario names that multiple scenario ID's match because they apply whether a specific checkbox is selected or not. Currently, I am still able to apply the correct name to the scenario by simply having multiple switch statements apply to the same scenario name. For example: PHP Code: switch(scenarioID){ case "0-0011100-101100": var scenarioName="Scenario 1"; break; case "0-1110011-101101": case "1-1110011-101101": var scenarioName="Scenario 2"; break; } However, I have some scenarios in which up to 3 options may apply whether or not they are checked. This means that I have to have 8 different switch cases (scenario ID's) for a single scenario name. Is there a way for me to wildcard the switch cases so that I can specify which items don't matter for a scenario? Something like the following example? PHP Code: switch(scenarioID){ case "0-0011100-101100": var scenarioName="Scenario 1"; break; case "*-1110011-101101": var scenarioName="Scenario 2"; break; } I'm trying to write a pi calculator that shows a comparison of the calculated value to the actual value. It works, but the output of the comparison shows only the first two decimal spots, followed by two 9s. Why is it showing two 9s and how can I make it more precise? Code:
<head>
<title>
Pi Calculator
</title>
<script language="JavaScript">
function calcpi(digitsn) {
p = 1;
s = 0;
for (c = 3; c < digitsn; c += 2) {
if (s == 0) {
p -= 1/c;
s = 1;
} else {
p += 1/c;
s = 0;
}
}
p *= 4;
return p;
}
function hid(input) { //Highlight Incorrect Digits
pi = "3.14159265358979323846".split('');
input = input.toString().split('');
result = "";
for (c = 0; c < input.length; c++) {
if (input[c] != pi[c]) {
//result += "; " + input[c] + "!=" + pi[c];
result += "<span style='background-color:red'>" + input[c] + "</span>";
} else {
result += input[c];
}
}
return result;
}
</script>
</head>
<body>
Repeat algorithm x many times:<br/>
<input type="text" value="10000" id="digitsx"/><br/>
<input type="button" onClick="document.getElementById('answer').value=calcpi(parseInt(document.getElementById('digitsx').value)).toString()" value="Calculate"/><br/>
Result:<br/>
<input type="text" readonly id="answer"/><br/>
Correct value:<br/>
<input type="text" readonly value="3.14159265358979323846"/><br/>
<input type="button" value="Compare" onClick="document.getElementById('comparison').innerHTML = hid('3.1499')"/>

Hello all. I'm working with a simple shopping page. I basically need to add up all of the values that are found in my query string, and display them as a total on my page. I know how to retrieve each value individually, however I'm a little confused on how to add up the values that are only found in the query string. Please keep in mind, I'm very new to javascripting, and probably won't understand in-depth coding. I have a lot more code to go with this, but I don't think it's required for my question.. Any help would be appreciated! Code: <javascript>
var parameters = new Array( );
// <![CDATA[
var qs = document.location.search.substring( 1, document.location.search.length );
var params = qs.split( "&" );
for (var x=0 ; x < params.length ; x++) {
var pair = params[ x ].split( "=");
parameters.push( new Parameter( pair[ 0 ], pair[ 1 ] ) );
}
function get_parameter_value_for_name( name ) {
for( var x = 0 ; x < parameters.length ; x++) {
if( parameters[ x ].name == name) {
return parameters[ x ].name;
}
}
return " ";
}
function get_parameter_value_for_value( name ) {
for( var x = 0 ; x < parameters.length ; x++) {
if( parameters[ x ].name == name) {
return parameters[ x ].value;
}
}
return " " ;
}

Strings,, Broken Links, and Variables --HELP! I have a page with over 600 lines of code that I need to fix, the problem is as such: The page contains about 200 links, the problem is that the link tags are all messed up,, instead of the URL's they all got replaced with xxxxx so instead of: <a href="http://mystore.com/product1">product1</a> it would read: <a href="http://mystore.com/xxxx">product1</a> each product has to link to it's own page .... i.e: product1 goes to /mystore.com/product1,,, and so on I need help writing a script or performing some sort of function, that will take the text in between the <a></a> tags and insert it into it's own tag instead of the xxxxx so it would see <a href="http://mystore.com/xxxx">BaseBall Gloves</a> and convert that line into <a href="http://mystore.com/BaseBall%20Gloves>BaseBall Gloves</a> -- OUTPUTS: the ideal way would be if it could replace the existing source (kind of how you can do a find and replace),, if that's not possible, it would need to output all the existing source code with the modified <a> tags to a new window, and then I can copy that code into a new page. I've tried using regular expressions and different functions but can't get it to work. I really appreciate your help.. Thanks. |
