查找所有ID以公共字符串开头的元素

问题描述：

我有一个XSL，它创建了ID为"createdOn"和$ unique-id的多个元素

I have a XSL that created multiple elements with the id of "createdOn" plus a $unique-id

Example : createdOnid0xfff5db30

我想使用JavaScript查找并将它们存储在变量中.我已经尝试过

I want to find and store these in a variable using JavaScript. I've tried

var dates = document.getElementsById(/createdOn/);

但这似乎不起作用.

答

使用jQuery，您可以使用

Using jQuery you can use the attr starts with selector:

var dates = $('[id^="createdOnid"]');

使用现代浏览器，您可以使用 CSS3属性值始于选择器以及 querySelectorAll :

Using modern browsers, you can use the CSS3 attribute value begins with selector along with querySelectorAll:

var dates = document.querySelectorAll('*[id^="createdOnID"]');

但是要回退旧版浏览器(且不使用jQuery)，您需要:

But for a fallback for old browsers (and without jQuery) you'll need:

var dateRE = /^createdOnid/;
var dates=[],els=document.getElementsByTagName('*');
for (var i=els.length;i--;) if (dateRE.test(els[i].id]) dates.push(els[i]);
