一个针对jQuery属性选择器的小例子,增加对jQUery属性选择器的理解: 复制代码 代码如下: <BR>a{ <BR>margin-right:20px; <BR>} <BR>ol{ <BR>position:relative; <BR>width:600px; <BR>margin-left:400px; <BR>} <BR>dt{ <BR>margin:10px; <BR>height:100px; <BR>background-color:#EAEAEA; <BR>border:3px dotted orange; <BR>} <BR>.showMessage{ <BR>width:380px; <BR>float:left; <BR>background-color:#D8D8D8; <BR>border:1px dotted red; <BR>} <BR> <BR>$(document).ready(function(){ <BR>var subject = ""; <BR>var describe = ""; <br><br>//name|="value" <BR>$("#attri1").bind("click",function(){ <BR>var topValue=$("#attri1").offset().top; <BR>subject = "Attribute Contains Prefix Selector [name|=\"value\"]"; <BR>describe = "Selects elements that have the specified attribute with a value either equal to a given string or starting with that string followed by a hyphen (-)."; <BR>$("a[hreflang|='en']").css("border","3px dotted green"); <BR>showMessage(subject,describe,topValue); <BR>}); <br><br>//name*="value" <BR>$("#attri2").bind("click",function(){ <BR>var topValue=$("#attri2").offset().top; <BR>subject = "Attribute Contains Selector [name*=\"value\"]"; <BR>describe = "Selects elements that have the specified attribute with a value containing the a given substring."; <BR>$( "input[name*='man']" ).val( "has man in it!" ); <BR>showMessage(subject,describe,topValue); <BR>}); <br><br>//name~="value" <BR>$("#attri3").bind("click",function(){ <BR>var topValue=$("#attri3").offset().top; <BR>subject = "Attribute Contains Word Selector [name~=\"value\"]"; <BR>describe = "Selects elements that have the specified attribute with a value containing a given word, delimited by spaces."; <BR>$( "input[name~='man']" ).val( "mr. man is in it!" ); <BR>showMessage(subject,describe,topValue); <BR>}); <br><br>//name$="value" <BR>$("#attri4").bind("click",function(){ <BR>var topValue=$("#attri4").offset().top; <BR>subject = "Attribute Ends With Selector [name$=\"value\"]"; <BR>describe = "Selects elements that have the specified attribute with a value ending exactly with a given string.
