如何在jquery插件中添加try catch块

Question

我有一个jQuery插件.我想在我的jQuery插件中添加try catch块以进行异常处理.

我的插件

$(document).ready(function(){
$('.requiredclass').keyup(function() {


$(this).pluginMethod();

});
});

(function($) {  //i Want try catch block for this part

// jQuery plugin definition

$.fn.pluginMethod = function(e) {

       return this.each(function() {
       var $this = $.this; 
       var som= $this.val();

            //My Code goes here  

        });
};

})(jQuery);

现在,如果我想添加try catch块,那么插件的外观如何？在jquery函数的情况下我们做这样的事情

功能

function myFunction() {
//varible declarations
try { 
    //Code goes here
}
catch(err) {  //We can also throw from try block and catch it here
    alert("err");
}
finally {
    //code for finally block
}
}

现在这是我们在函数的情况下知道的格式.但是如果我想在插件中添加异常处理,那么格式是什么？在从插件(function($) {的插件开始,然后有$.fn.pluginMethod = function(e) {后跟

       return this.each(function() {`. So where to start the try block and stop it,where to put catch block.Can any one suggest me the format.

如果有任何人对理解这个问题有任何疑问,请告诉我,我会尝试更详细地解释.

我不认为我真的得到你的问题.你需要更清楚.

但这是你想要的吗？

$(document).ready(function(){
    $('.requiredclass').keyup(function() {
    $(this).pluginMethod();
    });
});


try { 
    (function($) {
        //jQuery plugin definition
        $.fn.pluginMethod = function(e) {

           return this.each(function() {
               var $this = $.this; 
               var som= $this.val();
               //your Code goes here
           });
        };

    })(jQuery);
} catch(err) {  //We can also throw from try block and catch it here
    alert("err");
} finally {
    //code for finally block
}
