jQuery按背景颜色查找元素 [英] JQuery Find Elements By Background-Color

问题描述

尝试通过使用JQuery查找background-color属性设置为SelectedRowStyle背景色的行来访问GridView的Selected行.该颜色是#FF6600.我已经尝试过

Trying to access the Selected row of a GridView by using JQuery to find the row with the background-color attribute set to the SelectedRowStyle background color. That color is #FF6600. I've tried

var row = $("tr").find().css("background-color", "#FF6600");

但这只是将所有行设置为橙色.

But that just sets all the rows to orange.

var row = $("tr[background-color=#FF6600");

返回空

var row = $("tr").find().attr("background-color");

返回未定义

推荐答案

尝试 .filter 方法.

Try the .filter method.

var rows = $('tr').filter(function(){
    var color = $(this).css("background-color");
    return color === "#FF6600" || color === "rgb(255, 102, 0)" ;
});

我还没有测试过，可能需要调整rgb部分以解决间距问题.

I haven't tested it, the rgb part may need to be adjusted to account for spacing.

或更妙的是，这考虑到了大写还是小写

or better yet, this takes into account uppercase vs lowercase

var rows = $('tr').filter(function(){
    var color = $(this).css("background-color").toLowerCase();
    return color === "#ff6600" || color === "rgb(255, 102, 0)" ;
});
