系統從jq 1.4.2升級到1.7.1時發現，jquery.validate.js 在IE下無法正常工作，單步除錯進去和FF對比發現這段程式碼返回的結果不一致：

return $([]).add(this.currentForm.elements)
	.filter(":input")
	.not(":submit, :reset, :image, [disabled]")
	.not(this.settings.ignore)
	.filter(function () {
	    !this.name && validator.settings.debug && window.console && console.error("%o has no name assigned", this);
	    // select only the first element for each name, and only those with rules specified
	    if (this.name in rulesCache || !validator.objectLength($(this).rules()))
	        return false;
	    rulesCache[this.name] = true;
	    return true;
	});
 

$($.makeArray(this.currentForm.elements))...
