What is the best way to get an element by its class name using JavaScript?

我能否使用文件等东西?

最佳回答

Yup,有以下几件事情:getElementsByClassName(,此处还有browser support list ,其中“除I8和以下”

var elements = document.getElementsByClassName( myClass );

另外,还有querySelectorAll(),其中使用了安保部的甄选人员。 这与“贱民”的所作所为相当。 http://caniuse.com/#search=queryse”rel=“nofollow”> 这里还有一份浏览器支持清单。 “除IE7和以下所有最近浏览器”

var elements = document.querySelectorAll( .myClass );
问题回答

我更喜欢 j。 询问:

var elements = jQuery(".myClass");

这将收集所有内容,并按类别 = “米Class”。 如果你想要篡改这些内容,那么:

jQuery(".myClass").each( function() {
    // Getting element:
    var element = jQuery(this);

    doSomeStuff(element)
});
