javascript - jQuery function works intermittently -

i'm pretty stuck here.

i'm using live search lookup script (ajax) lookup customers in database using input field. upon selection click chosen customer. form filling out customer filled details database. problem of time once clicked fields populated data. intermittent, if repetitively click same customer populate, appears though works in bursts , fails appears though there no pattern.

thanks in advance :)

try using code below, instead yours. also, please, check comments explaining think wrong code.

jquery(function(){     jquery(".search").on("keyup", function() {         var searchid, datastring;         searchid = jquery(this).val();         datastring = "search=" + searchid;         if (searchid) {             jquery.ajax({                 type: "post",                 url: "search.php",                 data: datastring,                 cache: false,                 success: function(html) {                     jquery("#result").html(html).show();                 }             });         }     });     jquery(document).on("click", function(e){         //no need use "live" here since whole block of code executed once dom ready         var $clicked = jquery(e.target);         if (!$clicked.hasclass("search")) {             jquery("#result").fadeout();          }     });     jquery("#searchid").on("click", function(){         jquery("#result").fadein();     });     //this attached once since "#results" div there beginning , change content, don't remove , attach again.     jquery("#result").on("click", ".selection", function(e){         //you getting jquery(e.target) assume wasn't wanted since getting element clicked inside "#result" , not "#result" (that find content , assign values based on it)         var $clicked = jquery(this);         jquery('#custid').val($clicked.find('.customerids').text().trim());         jquery('#firstname').val($clicked.find('.firstnames').text().trim());         jquery('#lastname').val($clicked.find('.lastnames').text().trim());         jquery('#companyname').val($clicked.find('.companynames').text().trim());         jquery('#streetaddressp').val($clicked.find('.streetaddresss').text().trim());         jquery('#suburbp').val($clicked.find('.suburbs').text().trim());         jquery('#statep').val($clicked.find('.states').text().trim());         jquery('#postcodep').val($clicked.find('.postcodes').text().trim());         jquery('#phonenumber').val($clicked.find('.phonenumbers').text().trim());         jquery('#emailaddress').val($clicked.find('.emailaddresss').text().trim());     });      });
