jQuery post return variable

I need to set the width of a table based on a Javascript variable coming from a jQuery post.

$.post("get.php", {this: 'that'}, function(data){ 
var width = data // eg '300'

? set table width to 'width'

I'm new when it comes to jQuery, I know how to set the return into a div tag, but I'm guessing that won't help me in this instance.

Solution

  • First convert to numeric value using parseInt then just set the width property of the jQuery object:

    var width = parseInt(data, 10);
$("#myTable").width(width);

    "myTable" should be changed to the ID of the actual <table> element.
