我希望制作的程序在单独点击每个元素时基本上会改变颜色。我已经让它工作到我可以点击一个页面的位置,这两个元素都可以改变颜色,但我需要它们彼此独立。我该怎么办呢?
document.onload = function()
{
document.onclick = changeTest("box0", "green");
};
function changeTest(id, color)
{
var element;
element = document.getElementById(id);
element.style.backgroundColor = color;
}
HTML :
<!DOCTYPE html>
<html lang="en">
<head>
<title>this will appear on the tab in the browser</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script src="onclick.js" type="text/javascript"></script>
<style type="text/css">
{
border: 0;
margin:0;
paddig: 0;
}
body
{
font-family:"Times New Roman"; serif;
font-size: 12pt;
}
.box
{
height: 10em;
width: 10em;
margin: 2px;
}
#box0
{
background-color: yellow;
}
#box1
{
background-color: red;
}
</style>
</head>
<body>
<div class="box" id="box0"></div>
<div class="box" id="box1"></div>
</body>
</html>

var box0 = document.getElementById("box0");
var box1 = document.getElementById("box1");
var color = "green";
function changeColor(box, color) {
box.style.backgroundColor = color;
}
box0.onclick = function() {
changeColor(this, color);
};
box1.onclick = function() {
changeColor(this, color);
};

知道你也可以使用addEventListener()方法进行此操作。

您必须将事件侦听器绑定到各个框。就这么简单。这样的事情(未经测试):
document.getElementById("box0").onclick = changeTest("box0", "green");
document.getElementById("box1").onclick = changeTest("box1", "green");

我会使用jquery:
html:
<body>
<div class="box" id="box0">box0</div>
<div class="box" id="box1">box1</div>
</body>
和脚本:
$( "#box0" ).click(function() {
changeTest("box0", "green");
});
$( "#box1" ).click(function() {
changeTest("box1", "red");
});
这是一个jsfiddle:
好的,没有jquery:
<body>
<div class="box" id="box0" onclick = "changeTest('box0', 'red');">box0</div>
<div class="box" id="box1" onclick = "changeTest('box1', 'green');">box1</div>
</body>
