Question

I stuck with following constellation:

JSBIN Example

I want a click function for Check Availibility that does a jquery ajax with a given url (i.e. http://kiris-alinda.de/temp/verify.php) checks if the attribute @ges has a value (ie ges=”1234″) or not (ie ges=””) and finally alerts “true” or “false”

XML Response with true: http://kiris-alinda.de/temp/verify_true.php
XML Response with false: http://kiris-alinda.de/temp/verify_false.php

Thanks a lot in advance for your feedback and an interesting discussion…

Answer 1

you can try this approach

$.ajax({     
    url: 'http://kiris-alinda.de/temp/verify.php',    
    type: 'GET',    
    datatype: 'xml',    
    success: function(responseValue) {  
        var gesVal = $(responseValue).find('ges').text();

        if(gesVal !=null && gesVal !=undefined && gesVal != ""){
              alert("true");
        }else{
              alert("false");
        }

    },     
    error: function(jqXHR, textStatus, errorThrown) {         
         //error handling goes here     
    } 
});
