问题描述
我正在学习 JavaScript，最近我一直在试验鼠标事件，试图了解它们是如何工作的.
I'm learning JavaScript and recently I have been experimenting with Mouse events, trying to understand how they work.
<html>
<head>
<title>Mouse Events Example</title>
<script type="text/javascript">
function handleEvent(oEvent) {
var oTextbox = document.getElementById("txt1");
oTextbox.value += "
" + oEvent.type;
if(oEvent.type=="click")
{
var iScreenX = oEvent.screenX;
var iScreenY = oEvent.screenY;
var b = "Clicked at "+iScreenX+" , "+iScreenY;
alert(b);
}
}
function handleEvent1(oEvent) {
// alert("Left Window");
}
</script>
</head>
<body>
<p>Use your mouse to click and double click the red square</p>
<div style="width: 100px; height: 100px; background-color: red"
onmouseover="handleEvent(event)"
onmouseout="handleEvent1(event)"
onmousedown="handleEvent(event)"
onmouseup="handleEvent(event)"
onclick="handleEvent(event)"
ondblclick="handleEvent(event)" id="div1"></div>
<p><textarea id="txt1" rows="15" cols="50"></textarea></p>
</body>

推荐答案
var table = document.getElementById("tableID");
if (table != null) {
for (var i = 0; i < table.rows.length; i++) {
for (var j = 0; j < table.rows[i].cells.length; j++)
table.rows[i].cells[j].onclick = function () {
tableText(this);
};
}
}
function tableText(tableCell) {
alert(tableCell.innerHTML);
}
