我正在学习
JavaScript,最近我一直在尝试鼠标事件,试图了解它们的工作原理.
@H_404_2@<html>
<head>
<title>Mouse Events Example</title>
<script type="text/javascript">
function handleEvent(oEvent) {
var oTextBox = document.getElementById("txt1");
oTextBox.value += "\n" + 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>
这是我一直试图理解的代码.任何人都可以帮我创建一个HTML表格,点击表格的单元格用户被告知单元格,他正在点击？
被困在它的时间,谢谢帮助.
解决方法
@H_404_2@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);
}
是你可以做的一个例子. DEMO
