AJAX を使用してテーブル行のクリックを実装しようとすると、非常に奇妙な問題が発生します。これは、行をクリックするために使用する JS コードです。
//for tabs
$(document).ready(function () {
$("#tabs").tabs();
});
$(window).load(function() {
jsf.ajax.addOnEvent(function (data) {
if (data.status === "success") {
$("#tabs").tabs();
}
});
});
$("tr").not(':first').hover(
function () {
$(this).toggleClass('highlited');
// $(this).css("background","#707070");
},
function () {
$(this).toggleClass('highlited');
// $(this).css("background","");
}
);
function highlight(param) {
var row = jQuery(param).parent().parent().children();
row.toggleClass('highlited');
// row.css("background","#707070");
}
var inputs = document.getElementsByTagName("INPUT");
for (var i in inputs) {
if (inputs[i].checked) {
highlight(inputs[i]);
}
}
//for clicking on a row and opening new page
function addOnclickToDatatableRows() {
//gets all the generated rows in the html table
var trs = document.getElementById('form:dataTable').getElementsByTagName('tbody')[0]
.getElementsByTagName('tr');
//on every row, add onclick function (this is what you're looking for)
for (var i = 0; trs.length > i; i++) {
var cells = trs[i].cells;
for(var j=1; j < cells.length; j++){
cells[j].onclick = new Function("rowOnclick(this.parentElement)");
}
}
}
function rowOnclick(tr) {
var elements = tr.cells[0].childNodes;
for(var i = 0; elements.length > i; i++) {
if ((typeof elements[i].id != "undefined") && (elements[i].id.indexOf("lnkHidden") > -1)) {
//opne in a new window// window.open(elements[i].href);
location.href=elements[i].href
break;
}
}
return false;
}
これは JSF ページです。

AJAX コードを削除すると、データテーブル行をクリックして新しいページを開くことができます。しかし、最初のページにテーブルをロードするときに AJAX コードを追加すると機能しますが、2 番目のページに切り替えると JS コードが機能しません。多分問題は何ですか？また、ヘッダーとフォームの最後で JS コードを 2 回呼び出します。
