jQuery 属性选择器element[herf*='value']使用示例_jquery

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:

a{ margin-right:20px; } ol{ position:relative; width:600px; margin-left:400px; } dt{ margin:10px; height:100px; background-color:#EAEAEA; border:3px dotted orange; } .showMessage{ width:380px; float:left; background-color:#D8D8D8; border:1px dotted red; } $(document).ready(function(){ var subject = ""; var describe = "";

//name|="value" $("#attri1").bind("click",function(){ var topValue=$("#attri1").offset().top; subject = "Attribute Contains Prefix Selector [name|=\"value\"]"; 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 (-)."; $("a[hreflang|='en']").css("border","3px dotted green"); showMessage(subject,describe,topValue); });

//name*="value" $("#attri2").bind("click",function(){ var topValue=$("#attri2").offset().top; subject = "Attribute Contains Selector [name*=\"value\"]"; describe = "Selects elements that have the specified attribute with a value containing the a given substring."; $( "input[name*='man']" ).val( "has man in it!" ); showMessage(subject,describe,topValue); });

//name~="value" $("#attri3").bind("click",function(){ var topValue=$("#attri3").offset().top; subject = "Attribute Contains Word Selector [name~=\"value\"]"; describe = "Selects elements that have the specified attribute with a value containing a given word, delimited by spaces."; $( "input[name~='man']" ).val( "mr. man is in it!" ); showMessage(subject,describe,topValue); });

//name$="value" $("#attri4").bind("click",function(){ var topValue=$("#attri4").offset().top; subject = "Attribute Ends With Selector [name$=\"value\"]"; describe = "Selects elements that have the specified attribute with a value ending exactly with a given string. The comparison is case sensitive."; $( "input[name$='letter']" ).val( "a letter" ); showMessage(subject,describe,topValue); });

//name="value" $("#attri5").bind("click",function(){ var topValue=$("#attri5").offset().top; subject = "Attribute Equals Selector [name=\"value\"]"; describe = "Selects elements that have the specified attribute with a value exactly equal to a certain value."; $( "input[value='Hot Fuzz']" ).next().text( "Hot Fuzz" ); showMessage(subject,describe,topValue); });

//name$="value" $("#attri6").bind("click",function(){ var topValue=$("#attri6").offset().top; subject = "Attribute Not Equal Selector [name!=\"value\"]"; describe = "Select elements that either don't have the specified attribute, or do have the specified attribute but not with a certain value."; $( "input[name!='newsletter']" ).next().append( " ; not newsletter" ); showMessage(subject,describe,topValue); });

//name$="value" $("#attri7").bind("click",function(){ var topValue=$("#attri7").offset().top; subject = "Attribute Starts With Selector [name^=\"value\"]"; describe = "Selects elements that have the specified attribute with a value beginning exactly with a given string."; $( "input[name^='news']" ).val( "news here!" ); showMessage(subject,describe,topValue); });

//name$="value" $("#attri8").bind("click",function(){ var topValue=$("#attri8").offset().top; subject = "Has Attribute Selector [name]"; describe = "Selects elements that have the specified attribute, with any value. you can click the div which have id element"; $( "div[id]" ).one( "click", function() { var idString = $( this ).text() + " = " + $( this ).attr( "id" ); $( this ).text( idString ); }); showMessage(subject,describe,topValue); });

//name$="value" $("#attri9").bind("click",function(){ var topValue=$("#attri9").offset().top; subject = "Multiple Attribute Selector [name=\"value\"][name2=\"value2\"]"; describe = "Matches elements that match all of the specified attribute filters."; $( "input[id][name$='man']" ).val( "only this one" ); showMessage(subject,describe,topValue); });

});

function showMessage(subject,describe,topValue){ $("#showMessage").html(" "+subject+" "+describe) .addClass("showMessage").css("margin-top",topValue).hide().show(1000); }
