javascript - Delete element from a associative array in JavsScript --> very slow? -


i want delete 1 element associative array. array follows:

array[propertyname] = property;

this array filled data (less 10 entries) , shown in property window.

on pages can click delete button next entries , delete corresponding entry. achieve function called:

$d(document).on('click', '.property_del[type="button"]', function(event) {    (property in selectedgroup.properties) {       if(property == $d(this).attr('id').replace("_buttondel", "")){          continue;       }else{          temp_array[property] = selectedgroup.properties[property];       } selectedgroup.properties = temp_array; });

this works far, selected entry deleted after button click event, slow hell. second method delete slow first one:

delete selectedgroup.properties[$d(this).attr('id').replace("_buttondel", "")];

what can make faster?

thx!!

maybe jquery selector inside loop slowing things down. speed things up:

$d(document).on('click', '.property_del[type="button"]', function(event) {    var value = $d(this).attr('id').replace("_buttondel", "");    (property in selectedgroup.properties) {       if(property == value){          continue;       }else{          temp_array[property] = selectedgroup.properties[property];       } selectedgroup.properties = temp_array; });
