javascript - 如何将 onmousemove 函数的最终值放入变量中？

Question

我正在做一个jsp页面，它记录了鼠标在该页面上的时刻。我有记录时刻的代码，但我不知道如何将总时刻的最终值传递给变量？

<div onmousemove="myMoveFunction()">
  <p>onmousemove: <br> <span id="demo">Mouse over and leave me!</span></p>
</div>


<script>
var x = 0;

var y = 0;

var z = 0;


function myMoveFunction()
 {

    document.getElementById("demo").innerHTML = z+=1;
}
</script>

Answer 1

在使用之前，您必须指定您的处理程序。

<script>
var x = 0;

var y = 0;

var z = 0;

function myMoveFunction() {
  document.getElementById("demo").innerHTML = z += 1;
}
</script>

<div onmousemove="myMoveFunction()">
  <p>onmousemove:
    <br> <span id="demo">Mouse over and leave me!</span></p>
</div>
