javascript等待返回函数转换为onclick

Question

We have this code (using DHTMLX and DHTMLXMESSAGE):

myCheckBox.attachEvent('onEditCell', function(stage,rId,cInd,nValue,oValue){
        dhtmlx.confirm({
            type:"confirm",
            text: "Are you sure?",
            callback: function(result){
                if(result) {
                    return true;
                } 
                return false;
            }
        });
}); 

OnEditCell event should return "true" or "false" to validate action.

Now my code always check my checkbox and then show the confirm popup.

Answer 1

You can't make JavaScript block on asynchronous functions.

Have your event handler always return false.

Then trigger its functionality inside the callback instead of trying to return true.

Answer 2

You cannot return anything to attachEvent callback. Based on the result of your confirm checkbox, execute the relevant code

> callback: function(result){
>                 if(result) {
>                    //don't returnfrom here
                      // execute your code here only.
>                 } 
>                 

Hope this helps.
