View 24 RepliesIf it is possible to pass a php variable through to a javascript function.
Example.
I have a bit more to the code but that is the bare essentials as an example. If i remove the $id and $name from the passTest() for onClick the function works properly. However if I leave them in the function doesn't seem to work at all.
I have these 2 functions... The first draws a graph, then second I am trying to use to generate the "layout.addDataset" line of code, which it does perfectly. However, I am unsure how to call the function generatedataset from within drawGraph, and pass the variable "mainstring" as it is not set as a variable. code...

I am trying to pass a php variable to a javascript function using a link but it doesnt get through.
Code:
I have a javascript will a) look for a certain value in a drop down box and b) depending on what value is selected open up a div that includes link that when moused over will pop up with an alert box contain the passed parameter. A couple problems with this, one is I am not as sharp on Javascript as I am on PHP, and two, when I manually place a value into the function parameter, if it's a number it works fine, but if its a string or word, it comes up with an undefined error. why the undefined error is coming up only on strings or words?

Can I know how to pass a variable from one function to another using parameter.
The above code seem not working.
Let's say I have this function: function add(x, y) { var add = x + y;
[Code]...
So let's say the value of select_first is "1", and value of select_second is also "1". But when they are passed to the add function, the returned value is 11 and not 2. So what I understood is that it took the values as strings instead of integers. What should I do so that select_first and select_second are integers instead of string?
I have a bit of php that creates an entry on a page for each row in a table, some pages may have multiple entries, others just one.
eg.
<h2 class="title">{title}</h2>
{summary}
<p onclick="openBox({entry_id})">Click to read more ></p>
<div id="{entry_id}" style="display:hidden;">{body}</div>
I would like to have just one function to open and close all individually, eg.
$(document).ready(function(){
function openBox(id){
if ($("#id:first").is(":hidden")) {

Well I know I'm doing something wrong as this is not working, and I don't know how better to explain I hope this is sufficient, I'm not worrried about the php/html bit as that is working fine.
I'm working with the following code:
parent window:
Code:
<html>
<head>[code]....
Currently, the Code will open the child window, show a search box, search for the database and display links, when you click on the link, the parent window will show the variable passed. My question is, how would i change this so that each of the variables displayed would have a php variable that i could submit with a form?
Pass variable to jQuery function in another page? I have what I think is a simple question but I can't find an answer. I have two html pages - one.html, two html. [URL] one.html contains a jquery function that alerts the variable it is passed.

The problem is I want to call and pass the variable from another html page - two.html How can I call and pass a variable to the jQuery function in one.html from two.html ?
Might be a simple question, but I'm a Javascript and OOP newbie.
I have a form that I'm using Java & Ajax to dynamically validate while the user is typing (sort of, it actually executes the validate script after a 1 second pause in typing has passed). code...
<code>
<script type="text/javascript">
function interval_setting(){
var clear = 0;
clear =setInterval("xmlhttpPost11('index.cgi','tracker_shower','Latest_frame','Tracker_loader',clear,'','','')",20000);}
</script>
</code>
cant i pass variable clear like this ? Cause in xmlhttpPost if i give single quote to that variable it gives 'clear' not 0;
How do I pass a PHP variable into a window.onload event function? I have a URL that I need to pass to the JavaScript file that has this function in it. The JavaScript file itself is being linked from the PHP file that will pass the variable and I've seen many examples of how this is done via embedded JavaScript, but none where someone is linking to an external JavaScript file. I suppose this is probably a trivial matter to most of you, but I've never done this before and could use some guidance!

How to: pass local variable from <head> JS function to <body> textarea

I am writing a Javascript to sort and write out some stuff. PHP is not an option so I need to get this script working.
The problem arises when I want to make a link to the next page. (i.e. Like the link in google for the next 10 results)
I have <a href=# onclick=FUNCTION(VALUES)> written dynamically by the script.
It is written onto the document correctly, but the problem is, when the link is clicked, some seemingly random values are passed to the function.
I also have an invalid character error that arises when I pass the "whereVARquoted" variable into my function (code 2) which disappears when the variable is removed (code 1).
My code is below:
Code 1:
<script>
Code 2:

I start outside of the external JS file by: reviews.init(); reviews.initialiseContent('comment'); This loads my data and loads + sets the comment tab as default. My problem is that in the external JS file (shown below) the loadTabs variable will not allow me to pass it a variable: contentDiv.onclick = this.initialiseContent; Whenever I pass a variable here it errors, am I setting this up correctly, should I be using prototype for my this. variables? Interested to hear back on if this structure of code is the right way to go about this and also how I can pass a variable in this way :)

View 6 Replies View RelatedNormally, if you want to bind encapsulated event listeners to an object you have to test for support and then call the same function in different ways, for example:
if(typeof document.addEventListener != 'undefined')
{
document.addEventListener('click', someFunction, false);
}
else if(document.attachEvent != 'undefined')
{
document.attachEvent('onclick', someFunction);
}
But there's code repetition there - okay not very much, because it's just a function call ... but what if you wanted to use an anonymous function ..? Well you can't - the code repetition would be unacceptible.
Except that I've though of a way :) It's really obvious actually .. but I'm posting this in the hope that others will go "wow, that's blindingly useful" as I did when I thought of it :thumbsup:
Here it is - it takes advantage of square-bracket notation to use a string reference to the supported method:
//identify supported method of adding encapsulated event listeners
etype = (typeof document.addEventListener != 'undefined') ? 'addEventListener' : (typeof document.attachEvent != 'undefined') ? 'attachEvent' : 'none'
//set event name prefix
eprefix = (etype == 'attachEvent' ? 'on' : '');
//if encapsulated event listening is not supported, don't continue
if(etype == 'none') { return; }
so anonymous functions are built like this:
element[etype](eprefix + 'event', function()
{
... code ...
}, false);
Even though attachEvent doesn't require a third argument, it's ignored, so this syntax works for all.
