数组中删除某个元素

var strs=$("#bannerPhoto input[name='mendianbanners']").val();
var imgs = $(this).siblings('img')[0].currentSrc;

Array.prototype.indexOf  =   function(val)  {
    for (var  i  =  0;  i  <  this.length;  i++)  {
        if (this[i]  ==  val)  return  i;
    }
    return  -1;
};

Array.prototype.remove  =   function(val)  {
    var  index  =  this.indexOf(val);
    if (index  >  -1)  {
        this.splice(index,  1);
    }
};

var arr=strs.split('|');
arr.remove(imgs);
