using a javascript variable

I'm having trouble with this script recognizing my variable as a variable. The important part of the script is as follows:

    var content = 'imagereims';
    var ms = content.substring(5);
    $.get("../msimages/image.php", {ms: 'ms', pid: '<?php echo "$pid" ?>'}
    );

I want the script to recognize the variable ms as reims, but when the page displays it doesn't recognize the content of the variable. It just repeats ms. I've tried writing the variable without single quotes and with double quotes. I get the same result.

Any sugg开发者_StackOverflow社区estions. Thanks

You'll want to leave off the quotes on 'ms'. Try this:

var content = 'imagesreims'
var ms = content.substring(4);
$.get("../msimages/image.php", {ms: ms, pid: '<?php echo "$pid" ?>'});

'ms' is saying use this string literal as the value.

You'll also want a different substring. Try content.substring(6). content.substring(4) will yield 'esreims'.

As mentioned in another answer, you missed the ); at the end, which I've included in my answer.

Here's what you would do:

var content = 'imagesreims'
var ms = content.substring(6);
$.get("../msimages/image.php", {ms: ms, pid: '<?php echo "$pid" ?>'}

Note two things:

1. use ms as the variable, rather than the literal 'ms'
2. correct index 4 to 6, if you want reims

Current your line:

var ms = content.substring(4); 

is assigning ms the value esreims. See documentation here: https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/String/substring

All of these answers have pointed out errors in the code. You'll want to draw from them all.
