JavaScript - Index Values Of Strings As String Or Int?
I 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. Similar TutorialsThanks 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. basically what i want to do is this array[0] = 'hello'; array[1] = 'world'; array[2] = 'foo'; array[3] = 'bar'; delete array[1]; array.fillindex() /* new array value array[0] = 'hello'; array[1] = 'foo'; array[2] = 'bar'; notice how the key values shifted them self to compensate for the missing value. /* First off, I would like to thank everyone who has offered their help so far in my little self-appointed project dealing with astral body locations. I finally have the script working the way it was intended to and am looking at cleaning it up at this point. One of the things I would like to do in cleaning it up is change the way values are inputed when converting from Polar Coordinates to Cartesian Coordinates. The script is currently set up such that Right Accension is input in three fields identified as Hours, Minutes and Seconds. By the same token, the Declination Angle is input through three fields identified as Degrees, Minutes and Seconds. What I would like to do at this point is convert each set of three input fields to a single input field and allow the user to input the values as; Right Accension = 13:23:15.2 Declination Angle = 22:17:33 I understand that these would be inputed as String values and am familiar enough with the Split feature to extract the individual pieces of string (in this instance they would be 13, 23, 15.2 and 22, 17 and 33). What I am not familiar with, however, is converting those string values into numbers. I have done a bit of research into it and haven't really found anything that makes sense to me just yet, so if anyone can offer a bit of guidance, I am all ears. Not looking for anyone to specifically write the code for me, but if one of you fine folks could point me in the right direction as far as tutorials go, I would be thankful. GW 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!

In my coding, ys, ms, ds represents year starting, month starting, starting day... ye, me, de represents end... start,end gives file names in the format of yyyymmdd now i want to process files from 20100101 to 20100930 means from date is 2010/01/01 and to date is 2010/09/30 if i press submit button the files from 20100101 to 20100930 are processes here ys=2010 ms=01 ds =01 and ye=2010 me=09 de= 30 For this how do i call these textbox values (from date text box and todate) to another program (java) Thanks in advance. 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, 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! 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);
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:

Hello, I very new to this language and I still feel like I'm not grasping it... But, anyways, I'm doing a thing for school and I have to let the user input a string. I need to save the string and turn it into an array. For every word that is less than five letters I put "little" at the beginning of the word and for every word that is more than five letters I put "big" at the end of each word. Then I need to return the new string into output. I think I wrote the code really incorrectly, so any tips/advice would be much appreciated! Also, I don't understand adding user input into a code if that makes sense. The tutorials/lessons I've been looking at all say to put information into an array first and then mess with it. But, what if you don't have information in the array until the user puts it in? And once they enter it, then you mess with what they entered. I can't seem to get how to do that. Thank you for your time Code: function texter(newText){
var oldHTML = document.getElementById('outputPrompt').innerHTML;
document.getElementById('outputPrompt').innerHTML = newText+"<br />"+oldHTML;
console.log(newText);
}
function menuTwo(){
var userInput = document.getElementById('input').value;
var correctedInputArray = userInput.toLowerCase().split(" ");
var mainTwo = new Array([""]);
for(var i=0; i<correctedInputArray.length; i++){
var thisWord = correctedInputArray[i];
var lessFive = 5;
var moreFive = 6;
var restOfWord;
if(lessFive<5){
mainTwo[i]=thisWord+"-little";
}else if(moreFive>6){
mainTwo[i]="big-"+thisWord;
}
else{
restOfWord = thisWord.substr(1, thisWord.length-1);

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++) {

Hello everyone, I'm new to using regular expressions with javascript. I'm trying to search a string for instances of a substring with a particular prefix, followed by some numerical digits. So for instance my larger_string is: "This is a string ABCD12 EFGH124 ABCD76 EFGH90" And initially I want to find all substrings starting 'ABCD', with two following numerical digits. I can do it like this: var answer = larger_string.match(/ABCD\d\d/); But I'd really like to pass the 'ABCD' part in as a string itself, myString, as I'd then like to set myString to 'EFGH' and others, to repeat the search for those. I'm struggling with the syntax for creating a regular expression froma string. So I can do this: var reg = new RegExp("ABCD", "g"); but, this doesn't work: var reg = new RegExp("ABCD\d\d", "g"); and similarly I can do this: var myString = "ABCD"; var reg = new RegExp(myString, "g"); but, this doesn't work: var myString = "ABCD\d\d"; var reg = new RegExp(myString, "g"); What is it that I'm doing wrong here? Thank you Code: <html>

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. I am attempting to manipulate a long text string with javascript. This text string may have one or more occurrences of a string which starts with a particular string and ends with another string. So, for example, text that starts with 'nam' and ends with 'sit' in this example: Quote: Lorem ipsum dolor sit amet, consectetur adipiscing elit nam aliquam leo sit amet nibh tincidunt ultricies. Nullam nam feugiat velit sit amet dui scelerisque id ornare nulla ultricies. I want to prepend another string before the nam and append another after the sitt, to give me: Quote: Lorem ipsum dolor sit amet, consectetur adipiscing elit before nam aliquam leo sit after amet nibh tincidunt ultricies. Nullam before nam feugiat velit sit after amet dui scelerisque id ornare nulla ultricies. I think the way to do this is via RegExp, but I'm insufficiently familiar with this to know how to write the expression. Can anyone help me out? |
