JSF數據表的突出顯示行
[英]Highlight row of JSF datatable
問題描述
當鼠標指針位於行上時，我想在JSF表中突出顯示該行。 我找到了本教程 。
我嘗試在此處實現示例：

function () {

function () {

</div>
</div>
</div>
</h:body>
</html>
什么都沒發生。 我想JavaScript必須能夠工作。 突出顯示JSF表和普通HTML表中的行是否有區別？ 也許問題是JQuery的版本？
最好的祝願

問題是您的腳本在DOM完全加載之前就已執行。
您可以將腳本放在頁面底部，也可以在文檔准備好時調用它，方法是將其放在$(function() {}) ：
<script type="text/javascript">
$(function() {
$("tr").not(':first').hover(
function () {
$(this).css("background","yellow");
},
function () {
$(this).css("background","");
}
);
})
</script>

您可以在dataTable中使用以下js操作調用：
onrowmouseover="this.style.cursor='default';this.style.backgroundColor='#F1F1F1';"
onrowmouseout="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'"
