引用

$(window).load( function() {
        //do something    
    });

关于$(document).ready 和 $(window).load 的区别：
http://wuaner.iteye.com/admin/blogs/319769

下列代码会报该js错误：

$(document).ready(function() {

	$.validator.methods.atLeastOneChannel = function(value, element, param) {
		var n = 0;
		$("select").each(function (i) {
	        if (this.id == "fidsDispTempdataList.channelid" && this.value != "") {
		      	///alert(this.id + "    " + this.value);
		      	n+=1;
		     }
	     });
		return n >= 1;
	};
	
	
	$.validator.addClassRules("intClass", {
		digits:true
	});
	
     
	$("select").change(function () {
		if($(this).attr("id") == "fidsDispTempdataList.channelid") {
			///alert($(this).val());
			var curStartNumNode = $(this).parent().next().next().children().get(0);
			//var curPerPageNumNode = $(this).parent().next().next().next().next().children().get(0);
			//var curPagesNode = $(this).parent().next().next().next().next().next().next().children().get(0);
			var curPagesNode = $(this).parent().next().next().next().next().children().get(0);
			if($(this).val() == "") {
				$(curStartNumNode).rules("remove");
				//$(curPerPageNumNode).rules("remove");
				$(curPagesNode).rules("remove");
			} else {
				$(curStartNumNode).rules("add", {required: true});
				//$(curPerPageNumNode).rules("add", {required: true});
				$(curPagesNode).rules("add", {required: true});
			}
		}
	});
	
	
	//在遍历页面select时出的错
	$('select').each(
	   	function(){
	      	if($(this).attr("id")=="fidsDispTempdataList.channelid" && $(this).val()!="") {
		      	///alert($(this).val());
		      	var curStartNumNode = $(this).parent().next().next().children().get(0);
				//var curPerPageNumNode = $(this).parent().next().next().next().next().children().get(0);
				//var curPagesNode = $(this).parent().next().next().next().next().next().next().children().get(0);
				var curPagesNode = $(this).parent().next().next().next().next().children().get(0);
				try { 
					$(curStartNumNode).rules("add", {required: true});
					$(curPagesNode).rules("add", {required: true});
				} catch( error ) { 
					alert(error.message);
				}
		    }
	});
    
    
	$("#templateForm").validate({
		rules: {
			"fidsDispTemplate.code": {
				required: true
			},
			"fidsDispTemplate.name": {
				required: true
			},
			"fidsDispTemplate.mainPage": {
				required: true
			},
			"channelSpan" : {
				atLeastOneChannel : true
			}
		},
		messages: {
			"fidsDispTemplate.code": {
				required: "<s:text name='template.validation.code.required'/>"
			},
			"fidsDispTemplate.name": {
				required: "<s:text name='template.validation.name.required'/>"
			},
			"fidsDispTemplate.mainPage": {
				required: "<s:text name='template.validation.mainPage.required'/>"
			},
			"channelSpan" : {
				atLeastOneChannel : "<s:text name='template.validation.atLeastOneChannel'/>"
			}
		},
		errorPlacement: function(error, element) {
			///alert(element.attr("className"));
	     	if (element.attr("className") == "intClass error") {
		     	///error.insertBefore(element);
		     	return true;
	     	} else {
	       		error.insertAfter(element);
			}
		}
	});
	
});

经研究发现，是页面dom元素加载顺序导致的该问题。解决办法两个：
一将遍历select元素并对其做操作的出错代码 $('select').each()放至$("#templateForm").validate()之后（即$(document).ready()的最后面）：

$(document).ready(function() {

	$.validator.methods.atLeastOneChannel = function(value, element, param) {
		var n = 0;
		$("select").each(function (i) {
	        if (this.id == "fidsDispTempdataList.channelid" && this.value != "") {
		      	///alert(this.id + "    " + this.value);
		      	n+=1;
		     }
	     });
		return n >= 1;
	};
	
	
	$.validator.addClassRules("intClass", {
		digits:true
	});
	
     
	$("select").change(function () {
		if($(this).attr("id") == "fidsDispTempdataList.channelid") {
			///alert($(this).val());
			var curStartNumNode = $(this).parent().next().next().children().get(0);
			//var curPerPageNumNode = $(this).parent().next().next().next().next().children().get(0);
			//var curPagesNode = $(this).parent().next().next().next().next().next().next().children().get(0);
			var curPagesNode = $(this).parent().next().next().next().next().children().get(0);
			if($(this).val() == "") {
				$(curStartNumNode).rules("remove");
				//$(curPerPageNumNode).rules("remove");
				$(curPagesNode).rules("remove");
			} else {
				$(curStartNumNode).rules("add", {required: true});
				//$(curPerPageNumNode).rules("add", {required: true});
				$(curPagesNode).rules("add", {required: true});
			}
		}
	});
	
    
	$("#templateForm").validate({
		rules: {
			"fidsDispTemplate.code": {
				required: true
			},
			"fidsDispTemplate.name": {
				required: true
			},
			"fidsDispTemplate.mainPage": {
				required: true
			},
			"channelSpan" : {
				atLeastOneChannel : true
			}
		},
		messages: {
			"fidsDispTemplate.code": {
				required: "<s:text name='template.validation.code.required'/>"
			},
			"fidsDispTemplate.name": {
				required: "<s:text name='template.validation.name.required'/>"
			},
			"fidsDispTemplate.mainPage": {
				required: "<s:text name='template.validation.mainPage.required'/>"
			},
			"channelSpan" : {
				atLeastOneChannel : "<s:text name='template.validation.atLeastOneChannel'/>"
			}
		},
		errorPlacement: function(error, element) {
			///alert(element.attr("className"));
	     	if (element.attr("className") == "intClass error") {
		     	///error.insertBefore(element);
		     	return true;
	     	} else {
	       		error.insertAfter(element);
			}
		}
	});
	
	
	//将该段遍历页面select的出错代码移至ready()方法的最后，错误不再出现
	$('select').each(
	   	function(){
	      	if($(this).attr("id")=="fidsDispTempdataList.channelid" && $(this).val()!="") {
		      	///alert($(this).val());
		      	var curStartNumNode = $(this).parent().next().next().children().get(0);
				//var curPerPageNumNode = $(this).parent().next().next().next().next().children().get(0);
				//var curPagesNode = $(this).parent().next().next().next().next().next().next().children().get(0);
				var curPagesNode = $(this).parent().next().next().next().next().children().get(0);
				try { 
					$(curStartNumNode).rules("add", {required: true});
					$(curPagesNode).rules("add", {required: true});
				} catch( error ) { 
					alert(error.message);
				}
		    }
	});
});

二将将遍历select元素并对其做操作的出错代码从$(document).ready()中抽出来，放到$(document).ready()下面的$(window).load()中：

$(document).ready(function() {

	$.validator.methods.atLeastOneChannel = function(value, element, param) {
		var n = 0;
		$("select").each(function (i) {
	        if (this.id == "fidsDispTempdataList.channelid" && this.value != "") {
		      	///alert(this.id + "    " + this.value);
		      	n+=1;
		     }
	     });
		return n >= 1;
	};
	
	
	$.validator.addClassRules("intClass", {
		digits:true
	});
	
	
	$("select").change(function () {
		if($(this).attr("id") == "fidsDispTempdataList.channelid") {
			///alert($(this).val());
			var curStartNumNode = $(this).parent().next().next().children().get(0);
			//var curPerPageNumNode = $(this).parent().next().next().next().next().children().get(0);
			//var curPagesNode = $(this).parent().next().next().next().next().next().next().children().get(0);
			var curPagesNode = $(this).parent().next().next().next().next().children().get(0);
			if($(this).val() == "") {
				$(curStartNumNode).rules("remove");
				//$(curPerPageNumNode).rules("remove");
				$(curPagesNode).rules("remove");
			} else {
				$(curStartNumNode).rules("add", {required: true});
				//$(curPerPageNumNode).rules("add", {required: true});
				$(curPagesNode).rules("add", {required: true});
			}
		}
	});
	
	
	$("#templateForm").validate({
		rules: {
			"fidsDispTemplate.code": {
				required: true
			},
			"fidsDispTemplate.name": {
				required: true
			},
			"fidsDispTemplate.mainPage": {
				required: true
			},
			"channelSpan" : {
				atLeastOneChannel : true
			}
		},
		messages: {
			"fidsDispTemplate.code": {
				required: "<s:text name='template.validation.code.required'/>"
			},
			"fidsDispTemplate.name": {
				required: "<s:text name='template.validation.name.required'/>"
			},
			"fidsDispTemplate.mainPage": {
				required: "<s:text name='template.validation.mainPage.required'/>"
			},
			"channelSpan" : {
				atLeastOneChannel : "<s:text name='template.validation.atLeastOneChannel'/>"
			}
		},
		errorPlacement: function(error, element) {
			///alert(element.attr("className"));
	     	if (element.attr("className") == "intClass error") {
		     	///error.insertBefore(element);
		     	return true;
	     	} else {
	       		error.insertAfter(element);
			}
		}
	});
}); //the end of $(document).ready()




$(window).load( function() {
	$('select').each(
	   	function(){
	      	if($(this).attr("id")=="fidsDispTempdataList.channelid" && $(this).val()!="") {
		      	///alert($(this).val());
		      	var curStartNumNode = $(this).parent().next().next().children().get(0);
				//var curPerPageNumNode = $(this).parent().next().next().next().next().children().get(0);
				//var curPagesNode = $(this).parent().next().next().next().next().next().next().children().get(0);
				var curPagesNode = $(this).parent().next().next().next().next().children().get(0);
				try { 
					$(curStartNumNode).rules("add", {required: true});
					$(curPagesNode).rules("add", {required: true});
				} catch( error ) { 
					alert(error.message);
				}
		    }
	});
});
