引导程序开关的onInit回调，以检查元素的初始状态

Question

I need to check the current state of a particular bootstrap switch element on page-load and wanted to solve that with the onInit-Callback. Unfortunately it gives mit "undefined" when I ask for the current state. Here is my code so far...

$(".make-switch").bootstrapSwitch({
onText:'ja',
offText:'nein',
onColor:"success",
offColor:"warning",
indeterminate: true,
size:"big",
onInit:function(event,state)
    {
    var current_element=$(this).attr("id");
        if(current_element=="has-emotion")
        {

        alert(state); //gives me "undefined" for this and every other element


        }});

My Bootstrap-Switch Version is v3.3.2 and Jquery Version 2.1.4

What am I doing wrong here? Or is there an other way to check the state of the given element when loading the page?

Thank you very much! Regards from Austria

You can do this like :

$('.make-switch').bootstrapSwitch({        
    onInit:function (event, state) {                        
        alert($(this).is(':checked'));
     }
});
