Question

我知道,如何通过赋予这种权力来选择要素:

<input value="myvalue" />
$( input[value="myvalue"] )

But how it is possible to select dom elements with specified css rules set. For example i need to select all elements with css "background-position" set;

$( div ).filter(function() {
    return ($(this).css( backgroundPosition )); // tests for existence
});

However, the problem here is that even if background-position isn t set, some browsers set it to default values. You ll have to compare against those default values, but you won t be able to tell if those values were explicitly set in a stylesheet or not.

(Update: IE8 seecode>$ (this.css. ( backgroundPosition ), as “un Defin” no matter what. https://stackoverflow.com/questions/1420913/jquery-cs-bug-in-ie8” 准备测试背景、背景和/或背景页: 1 然而,虽然“should” 是“0%”,但“0px”公司报告说,“0px”为违约。两种测试。

(Update2: 富兰州没有归还个人财产,只是合并的背景材料;国际E8公司确实合并,只有个人。网络将同时进行。

$( div ).filter(function() {
   return ($(this).css( backgroundPosition ) !== "0% 0%" // firefox, webkit
        && $(this).css( backgroundPositionX ) !== "0px"  // ie8
        && $(this).css( backgroundPositionY ) !== "0px");
});
