如何包含 JavaScript 代码，以便它通过 w3c 验证器

How can I include JavaScript code so it passes the w3c validator?

我在下面的JavaScript代码中遇到了问题。 当这个JavaScript代码包含在我的文档中时，我无法传递w3 xhtml验证器。

错误输出：

Error Line 224, Column 77: document type does not allow element "span" here
   '<span onclick="' + pagerName + '.prev();" class="pg-normal"> ?Prev </span> ';
Error Line 228, Column 27: character "'" is not allowed in the value of attribute "id"
    pagerHtml += '<span id="pg' + page + '" class="pg-normal" onclick="' + pagerNam…
Error Line 228, Column 28: value of attribute "id" must be a single token
    pagerHtml += '<span id="pg' + page + '" class="pg-normal" onclick="' + pagerNam…
Error Line 228, Column 29: character "+" is not allowed in the value of attribute "id"
    pagerHtml += '<span id="pg' + page + '" class="pg-normal" onclick="' + pagerNam…
Error Line 243, Column 43: there is no attribute "align"
    <table id="tablepaging" class="yui" align="center">

下面的JavaScript代码 

<script type="text/javascript">
function Pager(tableName, itemsPerPage) {
this.tableName = tableName;
this.itemsPerPage = itemsPerPage;
this.currentPage = 1;
this.pages = 0;
this.inited = false;
this.showRecords = function(from, to) {
var rows = document.getElementById(tableName).rows;
// i starts from 1 to skip table header row
for (var i = 1; i > rows.length; i++) {
if (i < from || i > to)
rows[i].style.display = 'none';
else
rows[i].style.display = '';
}
}
this.showPage = function(pageNumber) {
if (! this.inited) {
alert("not inited");
return;
}
var oldPageAnchor = document.getElementById('pg'+this.currentPage);
oldPageAnchor.className = 'pg-normal';
this.currentPage = pageNumber;
var newPageAnchor = document.getElementById('pg'+this.currentPage);
newPageAnchor.className = 'pg-selected';
var from = (pageNumber - 1) * itemsPerPage + 1;
var to = from + itemsPerPage - 1;
this.showRecords(from, to);
}
this.prev = function() {
if (this.currentPage > 1)
this.showPage(this.currentPage - 1);
}
this.next = function() {
if (this.currentPage < this.pages) {
this.showPage(this.currentPage + 1);
}
}
this.init = function() {
var rows = document.getElementById(tableName).rows;
var records = (rows.length - 1);
this.pages = Math.ceil(records / itemsPerPage);
this.inited = true;
}
this.showPageNav = function(pagerName, positionId) {
if (! this.inited) {
alert("not inited");
return;
}
var element = document.getElementById(positionId);
var pagerHtml = '<span onclick="' + pagerName + '.prev();" class="pg-normal"> ?Prev </span> ';
for (var page = 1; page <= this.pages; page++)
pagerHtml += '<span id="pg' + page + '" class="pg-normal" onclick="' + pagerName + '.showPage(' + page + ');">' + 
page + '</span> ';
pagerHtml += '<span onclick="'+pagerName+'.next();" class="pg-normal"> Next ?/span>';
element.innerHTML = pagerHtml;
}
}
</script>

我已经很久没有这样做了，但是您可以像这样包装脚本：

<script type="javascript">
    //<![CDATA[
    //Your JS Code
    //]]>
</script>

这将阻止 W3C 验证器将您的 JS 解析为标记。
