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>

这是我一直试图理解的代码.谁能帮我创建一个 HTML 表格，在点击表格的单元格时，用户会被告知他正在点击的单元格?一直卡在上面，谢谢帮助.

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);
}

是你可以做的一个例子.演示
