I have the following javascript function:
<script type="text/javascript">
function HTMLEncode( text )
{
text = text.replace(/&/g, "&") ;
text = text.replace(/"/g, """) ;
text = text.replace(/</g, "<") ;
text = text.replace(/>/g, ">") ;
text = text.replace(/'/g, "'") ;
return text ;
}
</script>
Now i want to store the content of 'text' in a php string. Is that possible?
I tried and tried for so long to get this to work, but I just can't.
Here's what I did:
var testvar = document.getElementById('example').style.color;
alert(testvar);
Not only would the alert come up empty each time, but IE reports that "testvar" is undefined. Why isn't it working? And if I'm going about it the wrong way, how can I store an element's style info, such as font colour like in this example, as a variable?
I'm working on a page that needs to do some calculations based on values that the user inputs via sliders. I can get the values selected to display in a text box below the slider, but I also need to store the value as a variable for use in calculations.

I was wondering if someone could help me on a problem I have been having. In my code my function is supposed to take the elements of the form and it checks to see if it is checked or not. After that it would store it in the variable checkbox. However when I test it out it will not store it in the variable. For example if I picked sleep/ standby checkbox and hit submit it will show as 06 instead of just 6. Don't know what I am doing wrong. Here is my [code]...

I 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);
[Code]....
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.
When a person signs up for my website it first adds them to my external email list and then to my MySQL database.In order to do this you have to pass the information of the form to the next page where you can "display" it. Nothing except this display function seems to work.So what I am trying to do is take what is outputted by this display button and store it in a javascript variable. Then transfer this variable to a form which will auto submit and start the PHP registration pulling the output of the script, right now I can either get an undefined or the entire HTML code. Is there another option?Here is my code:

I kinda think that it has something to do with the escape quotation plus x, which I need so that the id won't duplicate.

This is calculator program that I have gotten stuck on. Here is where I think I am at:
The program is now taking the 1st number entered displaying it and storing it in the variable "memory".
Operation (+,-,*,/) is added to the memory in function action1() but then when the second number is entered it replaces memory with the second number. How can I get the variable memory to the whole string of 1st number,action, 2nd number?
Also once I do get that working correctly:
Wouldn't eval(document.calculator.display.value= memory) in my HTML for the "=" give me the calculation. (if I could figure out how to have memory store the 1st number and action1 and 2nd number all together) Or would eval(document.calculator.display.value) do it for me.

I'm writing a debugging script and I'm passing a function an object to iterate through:
myObject = {a:1,b:2}
debug(myObject);
I'm wondering if there is any way to get the variable's name as a string("myObject"), so something like a .name property:
function debug(obj) {
alert(obj.name); // would alert "myObject"
}
Is there any way to do this?
I need to look at the url, if a variable is present in the query string.

Say I had a bunch of elements with id names "id1", "id2". "id3" etc. Then say I had a function that adds a click handler such that when you click these elements it gets the id name with this.attributes[1].nodeValue;Then say I had a bunch of arrays with the same names as the ids var id1 = ["data", false, 45]; var id2 = ["otherdata", true, 15]; var id3 = ["otherotherdata", null, 65];. How would I set a variable "currentid" to the array with the corresponding name as the id name? I guess the underlying question is, how would I convert a string to a variable name?
View 1 Replies View RelatedI have a javascript program that currently takes the contents of a *.txt file and converts it to a string-type variable using a hidden iframe.
For my pruposes it would be much nicer to read a *.csv file instead, however the method I'm using creates the "open/save file" pop-up window.
All files are client-side and in the same folder on one computer; this is NOT server-side or internet-based. It is simply javascript used in an HTA file as programming code. The *.csv does not need to be edited, just read.
I need to know how to convert the text of this *.csv file into a string variable. I have heard of using "xmlHTTPRequest (AJAX)" but am not familiar with how to use this.

I'm using the alert to confirm if I've managed to get the time ok from the html, it should when working display the static time but currently displays NaN which AFAIK means that javascript is getting something from the HTML but it's in a form that it can't work with.
I know that the HTML validates fine, the time display is output from PHP. The intention is that PHP will output the time, if javascript is available then the javascript will take the static time and turn it into a ticking clock.
I'll look into the main guts of the clock script at another time, right now I need to get the basics working. I need to do it something like this way as I don't want to have any javascript embeded in the HTML, I want to have the javascript in external files.
I am designing a feedback page for my website and have carried info through the url to the feedback page from a previous page. This url contains a name of an individual, in between two symbols = and &
The url of the feedback page looks something like this:[URL].... First, I have used a form to display the information so that the user can see who they have selected, ie. extract the first and last names from the url. (The script following the form extracts the name from the url so that it can be displayed by the form, not exactly sure why it does so in this particular order but it seems to work so far).
This is the code I have used to do this:
<FORM NAME="SWnamefunc">
<div align="left">
<INPUT TYPE="hidden" NAME="yoyo" SIZE="35">

having trouble getting a query string/URL to append a couple of variables from a function (well, trying to get ONE working). Basically, once a user makes a selection from a form, I want the script to add the variable to the query string, which is then sent off to a PHP script. If I manually enter the 'social_housing_type' as a number in the query string, it executes properly, I just can't get it to do it from the form.

menu[i] should reference the "login" variable and then put one of the values for the login variable array in its place. So if menu is settings then the settings array would be used.
I have three drop down menus that when changed call a simple js
function, passing a value i.e.
<SELECT name="Team" onChange="change('national');">
the function defined at the beginning is
function change(which) {
current = document.premForm.Team.selectedIndex;
document.images.premShirt.src = "assets/shirts/"
+document.premForm.Team[current].value + ".gif";
}
the var 'which' is being passed succesfully, but i can't work out how
to change
document.premForm.Team.selectedIndex;
into
document.whichForm.Team.selectedIndex;
depending on what value the function receives. My 3 forms are called
premForm,nationalForm and worldForm
