本文介绍了使用JQUERY进行页面元素选择的方法，包括通过ID、元素名称、类名及通配符选择器来修改页面样式。
JQUERY对页面属性的选择控制（整理）
1.#id：通过元素id
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(document).ready(function(){
$("#myDiv").css("border","3px solid red");
});
</script>
<style>
div {
width: 90px;
height: 90px;
float:left;
padding: 5px;
margin: 5px;
background-color: #EEEEEE;
}
</style>
</head>
<body>
<div id="notMe"><p>id="notMe"</p></div>
<div id="myDiv">id="myDiv"</div>
</body>
</html>
2.element：通过页面元素名称，如div，span，p等
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(document).ready(function(){
$("div").css("border","3px solid red");
});
</script>
<style>
div,span {
width: 60px;
height: 60px;
float:left;
padding: 10px;
margin: 10px;
background-color: #EEEEEE;
}
</style>
</head>
<body>
<div>DIV1</div>
<div>DIV2</div>
<span>SPAN</span>
</body>
</html>
3..class：通过class名称，注意“.”号
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(document).ready(function(){
$(".myClass").css("border","3px solid red");
});
</script>
<style>
div,span {
width: 150px;
height: 60px;
float:left;
padding: 10px;
margin: 10px;
background-color: #EEEEEE;
}
</style>
</head>
<body>
<div class="notMe">div class="notMe"</div>
<div class="myClass">div class="myClass"</div>
<span class="myClass">span class="myClass"</span>
</body>
</html>
4.*:通过“*”号匹配所有
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(document).ready(function(){
$("*").css("border","3px solid red");
});
</script>
<style>
div,span,p {
width: 150px;
height: 60px;
float:left;
padding: 10px;
