jQuery implements ctrl enter (carriage return) to submit the form_jquery

Developed using jQuery plug-in development method. The specific code is as follows:

jQuery.fn.extend({
  /**
   * ctrl+enter提交表单
   * @param {Function} fn 操作后执行的函数
   * @param {Object} thisObj 指针作用域
   */
  ctrlSubmit:function(fn,thisObj){
    var obj = thisObj || this;
    var stat = false;
    return this.each(function(){
      $(this).keyup(function(event){
        //只按下ctrl情况，等待enter键的按下
        if(event.keyCode == 17){
          stat = true;
          //取消等待
          setTimeout(function(){
            stat = false;
          },300);
        } 
        if(event.keyCode == 13 && (stat || event.ctrlKey)){
          fn.call(obj,event);
        } 
      });
    });
  } 
});

How to use:

$("#textarea").ctrlSubmit(function(event){
  //提交代码写在这里
});

Isn’t it very simple and practical? I hope you all like it.
