使用foreach函数时的javascript异常

Question

I am trying to parse an associated array returned from a PHP functoin like this:

$.ajax({
        type: "GET",
        url: "../controllers/Checkpoint.php/getAllCheckpoints"
    }).done(function( result ) {
        result.foreach(function(index, value){
            alert(index + "  "+ value);
        });
    }).error(function(){

    });

i return the array like this in php

foreach($result as $row) {
            $checkpoints[$row['ID']] = $row['Name'];
        }
        return json_encode($checkpoints);

the result of that array reading from the chrome F12 console is

{"1":"check point 1","2":"check point 2"}

I got this error in the javascript code:

ReferenceError: forEach is not defined

could you help me please

I would suggest using the jQuery.each() generic iterator function in combination with the javascript JSON.parse() to accomplish what you are attempting to do.

jQuery.each()

JSON.parse

.done(function( result ) {
    checkpoints = JSON.parse(result);
    $.each( checkpoints, function( index, value) {
         alert(index + "  "+ value);
    });
});
