js this function call does not need to capture the id, name or tag name again_javascript tips

This is the node captured by the js you are currently executing. In this way, you can capture the id, name or tag name in js without writing methods such as document.getElement, saving some trouble. Usually obj is used instead.

Copy code The code is as follows:

<script> <br>function nullCheck(obj) <br>{ <br>...... //Write the code for the function you need here <br>} <br></script>



function clickAgenter(obj){
if($(obj).attr("checked")=="checked"){
$ ("[name='agentType']").removeAttr("checked");//Cancel all selections
$(obj).attr("checked","checked")
}
}
