I have used PHP to send a variable in the url and I then need to use Javascript to send it on again. How would I pick up the variable? It is passeed as var=x. I am fairly sure I know how to pass it on I jsut need to get this value into a variable.
View 4 RepliesI have a problem with the following code. It generates a
<FORM><SELECT><OPTION> list. There is no problem in the generating. The
problem is in the execution as follows.
It works fine in Mac IE with and without the <FORM></FORM>.
In Mac Netscape 6 the onChange does not activate if there is no
<FORM></FORM>. When I put it in a form as indicated below the value of
train.options.value is undefined. What am I doing wrong?
As I said there is no problem in IE and mayby other browsers. It may be
just a Mac Netscape 6 problem. Code:
The problem I am having is when the following script is executed within my page and the user submits the form, the variables passed to the GET array are duplicated only for the inputs created by my script. I have other inputs in the form that are created within the HTML of the page that work fine (i.e. they only try to pass their value once) but I cannot get my script to work properly.
Here is my script:
Here is an example of what the url looks like after the form containing this script has been submitted:
The input (segments) created in my page only submits itself once, while anything created by the script (segment_type_1, segment_type_2, etc.) submits itself twice with the second, blank value overriding the first, correct value.
I'm trying to reuse a script I have but, I'm not able to due to the fact I can't use some variables in a function.
I would like to know why I am not able to use passed variables in javascript.
For example: I call a function submit_data( 'newDomainForm', 'add_domain', 'list_div' ), in the function itself I would like to use the form name (first variable passed) as document.form.domain_name.value.
Later on I would like to use the div id: list_div in document.getElementById( div_id ).innerHTML. This doesn't work.
I have to put the name of the actual div like this: document.getElementById( 'result' ).innerHTML
And to get the value of a form element I have to put the actual name like this:
HTML Code:
I am wondering why:
$.post("remote.php",
{'f':a_searchtype, 'partial':value},
function(data){
$("#result").html(data);

causes javascript errors in unrelated sections of code.
The second version can be used in a common routine that doesn't know what is being passed.
I want to call a javascript function when a <span> is clicked, pass two variables to it, and then use jquery to hide that span.
A simple example is:
The variables (1,3) & (8,9) are loaded dynamically with a php script. Adding the two variables together isn't the intent of the script, but it seems the simplest way to explain what i'm after.
So how do you get $(this) to work in a function that has to have variables passed to it?
Is it true that Javascript has no clone() method, to pass an object by copy of value instead of reference?
If I have an object and want to make an array out of all of its instance variables, I can loop through it and pass its values to a new array, and the class instances will be passed by copy and not by reference?
Example 9.3: References Themselves Are Passed by Value
// This is another version of the add_to_totals() function. It doesn't
// work, through, because instead of changing the array itself, it
tries to
// change the reference to the array.
function add_to_totals2(totals, x)
{
newtotals = new Array(3);
newtotals[0] = totals[0] + x;
newtotals[1] = totals[1] + x;
newtotals[2] = totals[2] + x;
totals = newtotals; // this line has no effect outside of the
function.
}
Note that this rule applies not only to pass-by-reference, but also copy-by-reference. You can modify an object through a copy of a reference, but changing the copied reference itself does not affect the object nor the original reference to the object. This is a more intuitive and less confusing case, so we don't illustrate it with an example.
I had made a form in which dynamic rows are added to a table. Now when i send there values to next page by GETmethod then in between alphabets where space is given + is shown and where new line is there & is shown.

For example purposes, let's call the page "JQuery.asp", and we'll call the back-end "BackEnd.asp".My BackEnd.asp is set up as reusable code, using JQuery.asp as my wrapper.BackEnd.asp includes the following line:

I've made a trivial html page to show my problem. This page should take all of the <tr> tags from the first table, move them into the second table in reverse order, and change each <tr> tag's click handler to print it's internal <td> tag's contents.Unfortunately, the function I've set as the click handler seems to be passing a variable by reference rather than by value. I'm sure this is probably the expected behavior, but is there someway to prevent this behavior?If this doesn't sound very clear, hopefully the code I've included will make more sense:
<html>
<head>
<script type="text/javascript"

I have downloaded 2 html pages that give me page1 with a drop down box for a list, and a 'show' button. this then passes dropdown value to page2 and JS presents the text on the page, but I want to use the passed parameter to change the src of an img with ID=img1.can post all the JS if you like but assume i am missing just a one liner replacing the ....
var name = getValue("name");
document.write(name);
The code below is the relevant part to an autosuggest feature. The variable that isn't being passed is "firstValidIndex". It is being set appropriately, but when it is used in "sortArray()", its value is 0.

// firstValidIndex is the first index where the char is at the beginning of a string

I'm trying to limit the number of items that can be passed to the 'list1' select box to ten items. The way I have it now, it pops up a warning if user tries to pass more than ten, but then passes the first ten of the selected items through to list1 anyway. I don't want it to pass any items if they try to pass more than ten...just show the popup, and make them try again. Code:

So I have a function that is being passed an array of nodes: some of them plain vanilla DOM nodes, (say, those created by document.createElement), others are jQuery nodes (say $("<div></div>").
