将e.target传递给单击元素时调用的函数

Question

I am trying to pass the clicked event (event.target) to a function inside a function that is being called when clicked how would i do this?

function showGrid(){
    updateTag()
  }

function updateTag(){
    /*how do i get the event.target passed here? */
    alert(e.target) 
  }


$(".gridViewIcon").click(function(e) {
   showGrid();
  });

Answer 1

Just pass the event argument object down through your function calls.

function showGrid(e){
        updateTag(e);
  }

function updateTag(e){
    /*how do i get the event.target passed here? */
    alert(e.target); 
  }


$(".gridViewIcon").click(function(e) {
   showGrid(e);
  });

To include the argument into a nested jQuery function, you can create a closure on the variable like so:

 function updateTag(e){

        alert(e.target); 

        ...
        var x = e;
        something.each( function(i) {  alert(x.target); } );

      }

Answer 2

Add e as a parameter for each function you need to pass it too.

function showGrid(e){
        updateTag(e)
  }

function updateTag(e){
    /*how do i get the event.target passed here? */
    alert(e.target) 
  }


$(".gridViewIcon").click(function(e) {
   showGrid(e);
  });
