成功设置变量值

how can I set the variable dch to be the returned success ajax data?

var aid='11111111V';
var dch = 0;
$.ajax({
    type:"POST",
    url:"new_hpa_fun_aplcval.php",
    data:"aid="+aid,
    success: function(msg) {            
        if (msg =='OK'){
            dch=1;                    
        } else {
            dch=2;
        }
    }
});
if (dch==1){
     //same php code
}else if (dch==2){
     //another php code
}

    You can try like this

    1) Wrap the ajax within a function and return the value

    2) What does "async: false" do in jQuery.ajax()?

    function call() {
         var temp = 0;
         $.ajax({
            type:"POST",
            url:"new_hpa_fun_aplcval.php",
            async: false,  // Add this
            data:"aid="+aid,
            success: function(msg) {            
                if (msg =='OK'){
                    temp = 1;                    
                } else {
                    temp = 2;
                }
            }           
         });
         return temp;
        }        
    var dch = call();
