数组的ID - 如何用JavaScript / JQuery选择？ [英] Array of IDs - how to select with JavaScript / JQuery?

问题描述

我有一个元素标识符数组，从一些服务器端验证返回。 ID不带前缀＃。

解决方案

p>不要忘记老式的getElementById - 它不需要哈希的id。然后只需将jQuery的节点添加到jQuery对象中：

  var ids = ['jq-primarySearch'，'jq-n -CSS']; 
 var nodes = $ .map（ids，function（i）{return document.getElementById（i）}）; 
 var jqObj = $（nodes）; 
  

I have an array of element identifiers, coming back from some server-side validation. The IDs aren't prefixed with a '#'. Rather than going through the array and prefixing a # to each member, is there jquery means of directly selecting all elements by their IDs?

解决方案

Don't you forget "old fashioned" getElementById - it doesn't require hashing the ids. Then just feed nodes to jQuery to get a jQuery object:

var ids = ['jq-primarySearch', 'jq-n-CSS'];
var nodes = $.map( ids, function(i) { return document.getElementById(i) } );
var jqObj = $(nodes);
