Question

我有一个JSF数据表。我想在选中相应的复选框时突出显示该行。我如何编辑JavaScript代码来实现这种效果？

Answer 1

我无法确定你的复选框在哪里或者他们的名字是什么，但我确实注意到你在脚本中使用了jQuery。我创建了一个快速的小 jsFiddle demo 来向您展示如何使用jQuery。在我的示例中，我创建了一个.highlight类，我将background-color设置为我想要的颜色。在jQuery中，我将所有复选框分组并附加一个 .change() 处理程序，我会在每次点击时打开/关闭高亮类。

<强> Check out the jsFiddle demo

HTML：

<div id="row-1"><input type="checkbox" id="chk-1" />Row 1</div>
<div id="row-2"><input type="checkbox" id="chk-2" />Row 2</div>
<div id="row-3"><input type="checkbox" id="chk-3" />Row 3</div>
<div id="row-4"><input type="checkbox" id="chk-4" />Row 4</div>

CSS：

div
{
    display: block;
    height: 20px;
    padding: 20px;
    border-bottom: dashed 1px #000;
}

input
{
    margin-right: 10px;
}

.highlight
{
    background-color: yellow;
}

jQuery的：

$("input[type=checkbox]").on("change", function() {

    var $chk = $(this),
        num = $chk.attr("id").substring(4),
        $row = $("#row-" + num);

    $row.toggleClass("highlight");

});

输出：

enter image description here

Answer 2

我的jQuery方法是这样的：

            <p:column >
                <h:selectBooleanCheckbox onclick="highlight(this)" />
            </p:column>

在CSS文件中创建.highlighted类：

.highlighted {
    background-color: red;
}

最后是实际功能：

          function highlight(param) {  
            var row = jQuery(param).parent().parent(); //children() available as well
                row.toggleClass('highlighted');
          }

您只需获得所点击row的{{1}}并处理checkbox的分配。直接和简单。

编辑：当然CSS class的数量取决于您的html元素组成。编辑了适合你的情况的功能，我尝试了不同的元素组成。

以下是我在选中复选框时让Javascript更改背景颜色的示例：

<html>
    <body>
        <table>
            <tr id="changeme1">
                <td><input type="checkbox" onclick="highlight('changeme1');" /></td>
                <td>Test Box</td>
            </tr>
            <tr id="changeme2">
                <td><input type="checkbox" onclick="highlight('changeme2');" /></td>
                <td>Test2</td>
            </tr>
        </table>
        <script>
        function highlight(id)
        {
            object = document.getElementById(id).style.backgroundColor;
            if(object == "yellow")
            {
                document.getElementById(id).style.backgroundColor = "white";
            }else{
                document.getElementById(id).style.backgroundColor = "yellow";
            }
        }
        </script>
    </body>
</html>
