JavaScript - I Need Help With Variables
I wrote a script: when the same button is clicked for the first time, it should give a message "Hello World", for the second time "hello Earth". The script is not working.
I don't want anybody to re-write the script, but to look at how i define variables and tell me where I am wrong. I think, this is where the main error is. my current script just outputs the message "hello world". my assumption is that functions can alter the value of a global variable. Thank you very much.

Similar TutorialsI hope someone can help me! I have a website that sells a product through a third party merchant - ie a customer clicks my "buy now" button and they are transfered to the merchants payment processing page. once the transaction is complete the customer is sent back to my thank you page where I give them some extra stuff for free. All pretty normal I guess. The problem is this - The merchant sends back some url parameters when they transfer the customer to the thank you page and I would now like to use the "customer name" parameter to personalise the thank you page to test if this makes any difference to my return rate. Now, whilst I am not a complete newbie I haven't got a clue how to achieve this. What I want to do is have the page display: "Hello [customer] .....etc..." The customer name parameter is passed as "cname" and is one of about a dozen passed seperated, presumably, by "&" Thanks for any help! Paul Noob here.

var X = '^(?=.*?(';
var Y = 'dog))(?=.*?(cat))(?=.*?(mouse'; // this gets created dynamically
var Z = ')).*$';
var A = X + Y + Z;
// result is ^(?=.*?(dog))(?=.*?(cat))(?=.*?(mouse)).*$ and is a valid and tested expression
var B = new RegExp(A, 'i');
I want to pass B to a search() function but it does not seem to be accepted as a valid expression anymore thanks for any help I have this code: Code: var player = 100;
var part1 = ('ctl00_cphRoblox_TabbedInfo_GamesTab_RunningGamesList_RunningGamesListView_ctrl0_ctl00_PlayersRepeater_ct');
var part2 = ('_PlayerImage1');
var final = part1 + player + part2;
var name = document.getElementById(final)
The variable (name) turns up null when I try to see what it is. But, it is, infact, an element on the page, and when I do it manually it works. Help? I am perplexed about this one. Not sure if php is the best solution or maybe javascript. ( or both.) I am writing a litle script that will go to my mysql table and take out 20 rows ( from about 10,000 rows ) based on the WHERE statement. Then I want to step through these 20 rows displaying just two filds in this fashion: First, I want to display one field in a "box" ( using divs and css ) then wait for a form input. Then while keeping the first displayed box and field display the second field in a similar box a fee lines below. Wait for a form input update some data. Then onto the next row. If I use javascript then I could keep all the processing on one page and not have to have server refreshes. But how do I get these those array elements from $row['field1'] and $row['field2'] into javascript vars ? Is this the best way to do this ? Or would php and having a couple of extra trips to the server for form processing be better ? Thanks for any input. . Hi, I'm looking to use the document function in javascript to change the TYPE of an INPUT. However I want to change the TYPE of the INPUT according to a variable passed to the javascript button, so i use: document.formname.inputname.value="newvalue"; I want to be able to change what inputname is depending on what is passed to the function, but right now firefox is telling me that it's undefined. Is there any way I can do this? Thanks in advance, Daniel Hi, I'm trying to make a calculator app; with a few differences. I have a text field with a numberpad below it, I got the numbers to show up in the text field, but am unsure as to how when I hit the enter button - it would store them in a variable?...I am also wondering as to how it would store current value and then allow me to input another value(maybe on the next page) and either subtract or add to it(the first value that is stored). I am also wondering how to get a decimal point in place(need it for currency). Any help would be greatly appreciated! Here is my code: Code: <html>
<head>
<script type = "text/javascript">
function decPoint(str){
if (str.indexOf('.') == -1) str += ".";
var decNum = str.substring(str.indexOf('.')+1, str.length);
if (decNum.length > 2)
{
alert("Invalid more than 2 digits after decimal")
}
else {
alert("Valid no")
}
}
var ent = document.write(document.getElementById("curamt").value);
</script>
</head>
<body border = "1"; color = "blue";>
<div id = "cur">
<p>amount is: <script>document.getElementById("amount").innerHTML = ent);</script>

All, I have the following code: Code: var http_request = false;
function makePOSTRequest(url, parameters) {
alert(parameters);
http_request = false;
if (window.XMLHttpRequest) { // Mozilla, Safari,...
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
// set type accordingly to anticipated content type
//http_request.overrideMimeType('text/xml');
http_request.overrideMimeType('text/html');
}
} else if (window.ActiveXObject) { // IE
try {
http_request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
http_request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {}
}
}
if (!http_request) {
alert('Cannot create XMLHTTP instance');
return false;
}
http_request.onreadystatechange = alertContents;
http_request.open('POST', url, true);
http_request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http_request.setRequestHeader("Content-length", parameters.length);
http_request.setRequestHeader("Connection", "close");
http_request.send(parameters);
}
function alertContents() {
if (http_request.readyState == 4) {
if (http_request.status == 200) {
result = http_request.responseText;
document.getElementById('myspan').innerHTML = result;
} else {
alert('There was a problem with the request.');
}
}
}
function getjob(obj) {
var poststr = "job_id=" + encodeURI( obj );
makePOSTRequest('getnextjob.php', poststr);
}
I call the getjob but doing the following: echo "<li><a href=\"#\" onclick=\"javascript:getjob($resultsetjob[job_id]); return false;\">$resultsetjob[name]</a></li>"; It's weird, only sometimes does it pass the variable and other times it doesn't. Is there a better way to do this?? Thanks in advance. Hi, I haven't used variable variables before and I'm still trying to get my head around it. I think I'm going OK but I have run into a fairly obscure little problem that I thought I'd throw out there to see if anyone has any ideas... The plan: to make a distance calculator that measures a line made by clicking on a google map. Overall distance is shown at the side, but segment length is shown in tooltip-like labels called Elabels. Segments can get dragged and segment length is updated as dragging occurs. Being that the number of segments (and labels) depends on the number of user clicks, I thought it would be a good idea to use the variable variable to keep all the references unique. If there's a better way to do this, I'd love to hear about it. The problem: it all works fine, except that, if you consider that dragging a point on a line changes two line lengths (let's say A is the start, B is the drag point and C is the end), only one length is updating - the A to B section. What I want is for the Elabel at C to reflect the change in the B to C line length as well. Anyway. Here's the page I'm working on. The relevant code is below. I've tried duplicating it and adding +1 to the variables (and every permutation thereof) but no dice. All I need really is for exactly what's happening now to be happening in the next Elabel along in the array. Any suggestions much appreciated. Code: function leftClick(overlay, point) {
count++;
var mar1= count-2;
var mar2= count-1;
var mar3= count;
var mar4= count+1;
window["label" + mar2]=new ELabel(point, dist ,"labelstyle",new GSize(10,10));
labels2.push(window["label" + mar2]);
map.addOverlay(window["label" + mar2]);
// Drag listener
GEvent.addListener(marker, "drag", function() {
drawOverlay();
window["marker" + mar2]=markers[mar1];
window["marker" + mar3]=markers[mar2];
window["marker" + mar4]=markers[mar3];
line = [window["marker" + mar2].getPoint(),window["marker" + mar3].getPoint()];
dist2=window["marker" + mar2].getPoint().distanceFrom(window["marker" + mar3].getPoint());
dist2="Segment<br> length:<br>"+dist2.toFixed(0)+"m";
if(parseInt(dist2)>10000){dist2=(parseInt(dist2)/1000).toFixed(1)+"km";}
window["label" + mar2].setPoint(marker.getPoint());
window["label" + mar2].setContents(dist2);
}
I am building a search function for a sermon blog on squarespace. The format url for category search is www.mysite.org/blog?category=... I have drop down menus and a datepicker but need to figure out how to get java to build the url and redirect to it. The output url should look like http://www.mysite.org/sermons?catego...+mybook+mydate. Any help would be greatly appreciated. Here is my java so far. Code: function search() {
var myRootSite = 'www.mysite.org/sermons?category=';
var myNewTitle = document.getElementById('myTextField').value;
var mySpeaker = document.getElementById('mySpeaker').value;
var myService = document.getElementById('myService').value;
var mySeries = document.getElementById('mySeries').value;
var myBook = document.getElementById('myBook').value;
var myDate = document.getElementById('myDate').value;
if (myNewTitle == 0 && mySpeaker == 0 && myService == 0 && mySeries == 0 && myBook == 0 && myDate == 0) {
alert('Please enter some search criteria');
return;
}
var title = document.getElementById('title');

Hello everyone. I am new to this forum and hope to become a good addition. Thanks in advance to whom ever might help. I am having trouble concatenating variables in the alert box. The alert will basically be: Sum of the numbers from 1 through 5 is 15. But the 5 is the var = userEntry and the 15 is the var = sumOfNumbers. Of course, the numbers 5 and 15 will be replaced by the userEntry and the calculated sumOfNumbers. I have been able to make the first variable work, but cannot get the second one. For example: alert (" Sum of the numbers from 1 through " + userEntry);. I just cannot figure out how to concatenate a second variable into the message. I hope I am making sense. I am new to javascript and working off of Murach's Javascript and jQuery. Thanks again! Hello to all! Can I have 2 variables upon one select? The code below is created dinamicly with php from a database, and displays a dropdown select box, the only thing is that the values: Oliver Franchis, Pedro pastor, Maria China... have unique ID's and when the name is selected I would like the ID allso to be. Code: <!-- Populate list with friends START-->
var newTextbox = document.createElement('select');
newTextbox.className = 'fn-select';
newTextbox.name = "opcion";
//First user in the populated select menu is the person Loged in
var op1 = new Option("", "Oliver Franchis");
newTextbox.appendChild(op1);
var txt1 = document.createTextNode('Me | Oliver Franchis');
op1.appendChild(txt1);
//Next users are my friends in the database
var op1 = new Option("", "Pedro pastor");
newTextbox.appendChild(op1);
var txt1 = document.createTextNode('Pedro pastor');
op1.appendChild(txt1);
var op1 = new Option("", "Maria China");
newTextbox.appendChild(op1);
var txt1 = document.createTextNode('Maria China');
op1.appendChild(txt1);
var op1 = new Option("", "Juan Testing");
newTextbox.appendChild(op1);
var txt1 = document.createTextNode('Juan Testing');
op1.appendChild(txt1);
var op1 = new Option("", "Carmen Hernandez");
newTextbox.appendChild(op1);
var txt1 = document.createTextNode('Carmen Hernandez');
op1.appendChild(txt1);
var op1 = new Option("", "Eduardo Palote");
newTextbox.appendChild(op1);
var txt1 = document.createTextNode('Eduardo Pajote');
op1.appendChild(txt1);
editAreaText.appendChild(newTextbox);

Hello, I am using javascript to dynamically edit a form and have run into some problems. In this excerpt of code "x" is already defined, "num" is already defined, and "eval(q)" is just pointing to the proper field in the proper form. Code: eval(q).onkeydown=function onkeydown(event)
{
checkLength(event,x,num,5);
};
Now the problem is, it is literally calling the function with "x" and "num" instead of their values. I tried "eval(x)" and "eval(num)" but that literally calls it with that whole statement as the parameter. How can I call this with the actual values inside of x and num? Thank you. Hi! I am trying to use innerHTML but unsuccessfully on my Wordpress website. Please see the following code: Code: var string = "<?php the_content(); ?>";
function textchange() {
document.getElementById('box_content_slideshow').innerHTML = '<div class="box_content">'+string+'</div>';
}
The problem is that when wordpress puts the content in the variable 'string', it automatically adds carriage returns/line break result in: Code: var string = "<p>heading</p> <p>sample text</p> <p>more text</p>"; Is there any way I can remove the line breaks making the string like: Code: var string = "<p>heading</p><p>sample text</p><p>more text</p>"; I have tried using: Code: var string = (<r><![CDATA[
The text string goes here. Since this is a XML CDATA section,
stuff like <> work fine too, even if definitely invalid XML.
]]></r>).toString();
But this only works in FF, and not in IE, Opera, or Safari. Thanks a lot! Cheers! I have this code, (a snippet of it below) which works, but how can I simplify it instead of repeating all the same code for the 12 different checks I have to run. If whatColor == A1 I need the search variable to equal fashion If whatColor == A2 I need the search variable to equal photography etc. Thanks Code: if (whatColor == 'A1') {

can anyone tell me why this doesn't work please: <html> <head> </head> <body> <input type="hidden" name="ba1r1c1" value="hello"> <script language="text/javascript"> ba1r1c1.value = "goodbye"; document.write(ba1r1c1.value); </script> </body> </html> thanks Ok i'm really new at this so i apologize beforehand if i ask a stupid question or anything. I'm working on a project that displays a GUI asking for a name as well as grades. when you enter them all it runs the grades through a formula and opens another frame with the results. I don't need any help building the GUI what i need help on is I cannot for the life of me find out how to access the variable from another frame. Everything i've seen online tells me to set the variable outside the class but i need to run the formula inside because the grades come from the user. Sorry if my code is messy, like i said i'm very new at this Code: // Loads all neccesary plugins

// fldr = 10%
// gp = 25%
asgnAvg = (a1 + a2 + a3 + a3 + a5 + a6 + a7 + a8 + a9 + a10) / 10;
projectAvg = (p1 + p2 + p3 + p4) / 4;
totalAvg = (asgnAvg * .20) + (projectAvg * .45) + (fldr * .10) + (gp * .25);
}
{
JFrame frame = new JFrame ("Student Average");
frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(new SInfo2());
frame.pack();
frame.setVisible(true);
// Show the frame
frame.setSize(300, 300);
setBackground (Color.gray);
frame.setVisible(true);
}
}
}
}
And this is the second frame i am trying to open i haven't really done anything for the GUI i'm just working on it reading the variables now Code: // Loads all neccesary plugins
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class SInfo2 extends SInfo
{
// Setting all text fields, labels and button
public JLabel Sname, AsgnAvg, ProjectAvg, TotalAvg;
public SInfo2()
{
setLayout (new GridLayout (4,2));
{
Sname = new JLabel (Sname); // These are the 4 I cannot retrieve
AsgnAvg = new JLabel (asgnAvg); // These are the 4 I cannot retrieve
ProjectAvg = new JLabel (projectAvg); // These are the 4 I cannot retrieve
TotalAvg = new JLabel (totalAvg); // These are the 4 I cannot retrieve
add (Sname);
add (AsgnAvg);
add (ProjectAvg);
add (TotalAvg);
}
}
}
Thank you in advance for anyone who even looks at it |
