jquery获得div数组中元素的id的方法 6C

我把多个div都放在数组里,我该怎么使用$操作符来把数组元素赋给一个新变量?普通情况是var div = $(''#div1''),我这种情况该怎么写?

5个回答

 var arr=['div1','div2','div3'];
 for(var i=0;i<arr.length;i++){
    var div = $('#'+arr[i]);
 }
 var divarr=[];
 for(var i=0;i<divarr.length;i++){
    var div = $(divarr[i]);
 }




var divArray=$('body').find('div'); $each(divArray,function(i,mydiv){ mydiv.text(i); });

用jquery的each函数。
$("div").each(function(i,element){

})
index - 选择器的 index 位置
element - 当前的元素(也可使用 "this" 选择器)

var array = ['#div1','#div2','#div3'];

var divs = $(array.join(','));
