I have the variable myNumber in a javascript script.myNumber contains the digit 44 in it. I can print myNumber in many ways (alert, document.write..) but I do not want to do this, I do not want to see 44 in a browser, I need 44 written in the source code so my parser can pick it up.
The problem: myNumber is a dynamic variable, its value changes, that's why I cannot write it down like this: var myNumber="44";
I'm pretty new to JavaScript and am having a problem. I thought what I am doing should work but it isn't.
Basically I have a form that people can put a quantity into. e.g. A, B, C.
I have a JavaScript function called comput that assigns values e.g. A = 5, B = 7, C = 9. Here is the start of the script:
<script language="JavaScript"><!--
function compute(form){
var A = form.A.value * 5;
var B = form.B.value * 7;
var C = form.C.value * 9;
I then declare a variable to add them up:
var ans = A+B+C;
return;
}
</script>
This part of the script works fine. Now I want to write the ans variable. So I use:
<script>
<!--
document.write ("Your total is "+ans+"")
// --></script>
But it isn't working. Any ideas?
I want to load an html div in a variable, modify it in another variable; and then change the document injecting the contents.
1. I load the html to be changed in a variable (code)
2. I modify an attribute of <param> using attr() and I put the result in a var (newcode)
3. I change the html in the doc
I've used the debugger, and all steps give the expected results, except of newcode.html(), which is a null string. Why?

Is there a function in javascript to get the source code of a page and contain it in a variable, or automatically obtain information from it in some way?For example, if I needed to get the title of a certain page, would I be able to somehow implement document.title to get the title of a webpage?
View 4 Replies View RelatedI need to write a script that parses a web page for a given delimiter and then stores the following 50 characters as a variable. I wrote the following php script:
Code:
<?php
$del = "picture_id";
$url = "http://xxxx.net/xxxxx/xxxxxx.php?do=xxxx";
$source = file_get_contents($url);

The delimiter is always going to be constant, however the succeeding characters will be different each and every time. I need to write this in Javascript because it is hosted on my server, and ran by users who post on my brothers message board (which is hosted elsewhere). Since Php is server side I always get "guest" as a value rather than the random string of characters like it should be.
I seem to have an issue with getting javascript to recognize the value of a variable.

View 8 Replies View RelatedI was wondering if it is possible to put all the non null variables of an array into a string variable with spaces between each array value? For example, if array() is a text array and has 10 values, array(0) through array(9), with three of those values null, let's say array(3), array(5), and array(7) are null, is there a way to put the remaining seven values into a string variable with spaces between each array value?

View 8 Replies View RelatedI've got an IFRAME it loads a page with variable contents. I need to know the WIDTH of the body of that page. I'm using offsetWidth and offsetHeight
Quote:
This is weird....offsetHeight returns the height of the document body. offsetWidth returns the width of the iframe!
Let me preface this with the usual disclaimer: I am new to this and have only been programming with Javascript, PHP for about 2 weeks now and have been lucky enough to have resolved the issues I have encountered. This one however is puzzling to me.
I have a HTML form created that collects member information. It calls, on submit, a confirmation page that lists all the data fields entered. This all works great. However, when I then post the variables from the first html form page from my second confirmation html page to my PHP script, using document.write with input type=hidden and inserting the address variable into the value field, the Javascript only passes this variable up to the first space. It is the only variable I pass that has a space in it.
I have verified that the variable does indeed contain the whole address and I have also verified when I execute the following: document.write ('<input type="hidden" name="address1" value='+address_1+'>');
the address_1 parameter passed to the php script only passes the string up to the first space.
I even tried to put fixed text in there instead of a variable (e.g.)
document.write ('<input type="hidden" name="address1" value="555 Drury Lane" >');
and it still only passes the string up to the first space (555).
I show the variable address_1 on my confirmation page and it shows the entire string.
I checked what was being passed and it seems that the Javascript is the culprit (or more likely the Javascript creator - me)
All my other variables (which don't have spaces) pass to the php script with no problems.
I got some code that loads divs from other web pages into a particular div in my main page. In other words, I click on a button, and this tells jquery to load afragment of a particular page into my main page. For instance if I have 5 web pages onrock stars, I could have 5 buttons, and each button could load one rockstar's biography into a div on the main page (and replace whatever was there before). This works, and I do see the content that it loaded. But when I do 'view source' in IE, I do not see that content (the bio of the rock star). Another clue that this content is not really there, is when I try and run some code on that content. The content (from those external pages) have divs with specific names, and I try and make them into collapsible panels by running the following short function:
var IdentifyPanels = function() {
$("DIV.ContainerPanel > DIV.collapsePanelHeader > DIV.ArrowExpand").toggle(
function() {
