• js object is an object obtained through dom operation, which refers to a label object on the page;

	var jsObj = document.getElementById("inpId");
	//将dom对象转化成jQuery对象
	var jqObj = $(jsObj);</script>

Convert jQuery objects into JS objects:

<script>
	//获取jQuery对象
	var jqObj = $("#inpId");
  	//将jQuery对象转化成JS对象
  	//方式一：
  	var jsObj1 = $inp[0];
    //方式二：
  	var jsObj2 = $inp.get(0);
 </script>
