I need to get the name of a select (#Dropdown) when its value is known but can\'t seem to get the syntax right. Here\'s an example:

I need to get the name of a select (#Dropdown) when its value is known but can't seem to get the syntax right. Here's an example:

$(document).ready(function()
{
   var countrycode = '55';
   var name = $("#Dropdown[value=countrycode]").text();  // fails here
   if(name == 'Germany')
   {..... etc

I can get it to work as follows in a different context when I'm 开发者_如何转开发able to use "this":

var name = $(this[value=countrycode]).text();

... but that's not available in the first example.

Anyone? Thanks.


You need to look for the option value within the select.

var countrycode = '55';
var name = $("#Dropdown option[value="+countrycode+"]").text();


You're including "countrycode" literally in your selector string.

There's probably a better way to do it, but this should work:

var name = $("#Dropdown[value=" + countrycode + "]").text();


Post also HTML, it seems kind of wrong - you can have just one ID (#something) per page, so there would be no need for something like #id[value=*].


try:

var name = $("#Dropdown option[value=" + countrycode + "]").text()
