<A HREF="javascript:go()">+ Add Text</A>
but how do I pass a variable to the function in this hyperlink?

I have an iframe....
<iframe src="somepage.html?var="tom";vartwo="jane";varthree="peter"">
Now....that is all great...BUT, I need to pass another variable INTO the iframe like the others (var, vartwo, varthree) and I won't have that variable UNTIL I do some javascript function to extract a background color from a div tag. Basically, I have to pass a bgcolor into the iframe so the resulting page will then display itself with a color that matches the parent page. Its a backend process....basically, the backend app needs "backcolor=" appended to the iframe.....BUT the iframe is loading first...so how do I do this?
I'm trying to pass parameters using the jquery's ajax function, but I end up with a "function undefined" error message when I try.
I had trouble finding simple examples of ajax passing parameters with jquery.

I am having trouble passing the correct id to change the innerHTML. I have a jsp that display people and their address information. There could be several people in the list, so it is in a loop. That part all works good. There is a drop down list with countries in them. Based on the country they select, I want to change some of the text. Here is what I have:
<tr>
<td class="datashaded" valign="top"><font size="2"><b>Country:</b></font></td>
<td class="datashaded" valign="top">
[code]...
When I hardcoded the id= value, not matter which group I changed the country on, only the first one was changing, so I knew I needed unique ids for each group. There is more to the table, but this is the good part. When the onChange fires now, Nothing at all happens.
I have a function which is currently called twice on the same page. Part of the function is to apply an onkeyup event to a created element. The problem is that when the function is called twice the first created element calls the onkeyup function of the second element!
table_JD.length-1 = 0 for first element
table_JD.length-1 = 1 for second element
updateSearch_TC_JD(1) is somehow called from first element!
newSearchBox.onkeyup = function() {updateSearch_TC_JD(table_JD.length-1)}
So this is my dilemma. I'm creating a function and passing variables dynamically, but when I try to pass a variable and then alert it out, I get an 'undefined' error.

I have this problem:
in my page index.asp I have defined a function rupload():
Code:
<%@ Language=VBScript %>
<% Option Explicit
Dim objConn, objRS, strSQL
[Code].....
In this way the function works perfectly; but I want that Ifile is not equal to a predefined path BUT Ifile must accept the value of javascript variable ip_file
Here is the code:
for (var i = 0; i < BS_crm['activityTypes'].length; i++) {
var clickFunc = function(){ activityList.showForm( -1, {blockType:[""+BS_crm['activityTypes'][i]['id'], "0"]} ); };
var type = {
[Code]....
Now, basically what I am doing here is running through one array to create an array of objects, that will be used to create links that will use whatever onClick function I pass it. The problem is that on the second line I need the BS_crm['activityTypes'][i]['id'] to be a value, not a reference. If that line was simply changed to:
var clickFunc = function(){ activityList.showForm( -1, {blockType:["3", "0"]} ); };
if this is such a obvious question, but i'm kind of newbie in JQuery, i am using a lightpop plugin, & i want to pass 'image_path' via html. lightpop plugin code is something like this:
(function(jQuery){
jQuery.browser = jQuery.extend(
{chrome: /chrome/i.test(navigator.userAgent)} ,
jQuery.browser

I'm trying to make it so when you click a cell in a table it runs a function based on the value within that cell. With the current code, no matter what cell is clicked, the alert box displays the same number, which is the last number in my array. The variable, princ, is just being overwritten rather than writing code to each the cell with the proper value.
for(i=0;i<=3;i++){
document.writeln('<tr>');
document.writeln('<th>'+(periodArray[i])+'</th>');

I have a DOM click event that creates a <span>. When the user clicks a button, it turns that <span> into a textarea that the user can type a new name in, press enter, and then the span contains the text the user input. Sort of like when you rename a file in Windows Explorer.
Anyway, the code is something like this, and I'm wondering if I can use 'area_el' in this way... right now it's giving me the error that area_el is undefined, even though I define it in the function that contains the Event declaration.The first part is the Dom stuff to make it all work. It's not stuff I need to mess with, but I'm putting it here in case it's useful.
var Dom = {
get: function(el)
{

I've been banging on this for a couple hours even though I'm sure it has a less-than-five-second fix. Hopefully somebody will glance at it and point out the obvious thing I'm missing.I'm using the onchange event of an html select element to trigger an array prototype function that looks for a value in an array and returns the indices of the array that contain that value, or FALSE if the array doesn't contain the value. For this example, here's the array being set up:
var instids = new Array();
instids[0] = 5;
instids[1] = 6;

I'm using Keith Wood's jquery plugin to produce some graphs for my site. Though I've been able to produce "static" ones, I'd like the user to be able to input a new constant and then have my graph update it according to what they enter. I'm not quite sure how to add the value that the user inputs to my linear function below. So far I have:
Code:
<input type="text" size="1" id="plotit2" name="plotit2"/>
for the user to input the desired change. Then I have:
Code:
$('#plotIt1').click(function() {
var svg = $('#svgplot').svg('get');
svg.plot.noDraw().addFunction('lingraph', linear, 'blue', 3).redraw();

I've parsed down the code to what I think are the important points but if I can clarify anything I'd be happy to do so.
how can I call a function by using the value of a variable name?i.e.
Code:
var str = "function_name";
// call 'function_name' by using its 'str' alias

I need to pass the 'id' variable from the event listener to the callback function, 'moveObject'. The moveObject function needs to know the id of which element it should act upon. How can I pass this variable?
View 3 Replies View RelatedI have a function in an external javascript file (calculate.js) which calculates the price of a product, based on a users preferences in a form (dropdowns, radio buttons etc). Each time the user modifies their choice, the script/function then displays the price on the page (index.html) using:
document.getElementById("price").innerHTML = price;
Once the user has finished making their choices, they then click the forms submit button (method="post") to be taken to a confirmation page (confirm.php).
Here, I can display the users preferences using php code like:
<?php echo $_POST['size'] ?>
<?php echo $_POST['color'] ?> etc, etc...
But I'm not sure how to pass the price over!
The preferences come from the form and are picked up with php. But the price is calculated with javascript! How do I send it to confirm.php?
I have tried adding
window.location = "confirm.php?Quote=" + price;
to the function, but this changes the page before the user may want to go to the confirmation page!
Can I add a hidden input to index.html with the value set as the javascript variable called price? If so, what syntax do I use for this? I have tried
document.write('<input type="hidden" name="quote" value="'price'" ?>" />')
and some other stuff too, but I still can't get it to work!
Or do I pass the value in the url, like confirm.php?Quote='price'? Again, what is the syntax, as I can't seem to get it to work?

I'm having trouble calling a function using a variable, from within a parent function. For instance:
function parent(){
function child(){
console.log("It worked")[code]....
That results in "TypeError: 'undefined' is not a function (evaluating 'window[test]()')"
how do i call a variable from a specific function in another function outside the first one?
View 4 Replies View RelatedI have a situation in which the function to be called is stored in a variable.

i'm having trouble with some of my codes.i've been trying to put variables in function calls parameters, but it just does not work.
for example, if I try to do sth like this:
Code:
//a function that creates page numbers based on number of pictures that can be shown on the page
function MenuBar() {
pageSpan = [document.createElement('span')];[code]....
when i try to run it, it won't work.what i'm trying to do is that every time the loop runs, the "onclick" event of the created span will be the value of the loops "x" variable -1, and the value of x variable.meaning, for every new span, the parameters in the showImage() function are different.
Code:
pageSpan[1].onclick = function () { showImages(0, 1) };
pageSpan[2].onclick = function () { showImages(1, 2) };
pageSpan[3].onclick = function () { showImages(2, 3) };
pageSpan[4].onclick = function () { showImages(3, 4) };
pageSpan[5].onclick = function () { showImages(4, 5) };
I can't seem to get a variable declared from within a post callback, so that I could manipulate my script accordingly. I have delete.php, that deletes an id from a mysql db. If it fails, I want the script to stop and display the error. The .php script echos an "ok" if everything went fine, if not - it echos the error.var abort_error; // set the error variable
$.get("delete.php", { delete: $(this).parent().parent().parent().attr('id') },
function(data){

Two objects on an html page. An event on object 1 effects object 2
$(".video_rg").mouseover(function(event){
var myTriggerId = event.target.id;
var myTargetId = 'video_' + myTriggerId;
document.getElementById(myTargetId).src = 'images/test_object_2.gif'; // this works
// $('#myTargetId').src = 'images/test_object_2.gif'; // this does not
});
My assumption (we know about those) is that I am not passing the data to the $() function correctly, that it is reading '#myTargetId' as a string, and not a variable. I just really want the JQuery code that would do what the document.getElementById code is doing.
Given the following code:
var xf2;
function f1()
{
if (document.createElement && document.body && document.body.appendChild) {
xf2 = new f2(arguments[]);
}
}
I am getting a syntax error in the "new" statement following the [].
How do I pass the variable-length arguments list received by f1 on to f2?
