1、判断是否为纯数字的js脚本：

 
$('#num').val()是通过jquery获取id=num的值
if(!/^\d+$/.test($('#num').val().trim())) {
	alert(非数字');
}

2、使用控制台调试js

function log(msg) {
	if(typeof console == "object") {
		console.log(msg);
	} else if (typeof opera == "object") {
		opera.postError(msg);
	} else if(typeof java == "object" && typeof java.lang == "object") {
		java.lang.System.out.println(msg);
	}
}

function someMethod() {
    log("调试跟踪");
}

3、时间比较


$('#projectTime, #prototypeTime, #appraisalTime, #prodModelTime').bind('focusout', function() {
			var now = new Date().valueOf();
			var $projectSection = $('input[name=projectSection]');
			var projectTime = $('#projectTime').val()==''?now+86400:new Date($('#projectTime').val()).valueOf();
			var prototypeTime = $('#prototypeTime').val()==''?now+86400:new Date($('#prototypeTime').val()).valueOf();
			var appraisalTime = $('#appraisalTime').val()==''?now+86400:new Date($('#appraisalTime').val()).valueOf();
			var prodModelTime = $('#prodModelTime').val()==''?now+86400:new Date($('#prodModelTime').val()).valueOf();
			switch(true) {
				case now < projectTime:
					$projectSection.val("评估阶段");
					break;
				case now >= projectTime && now < appraisalTime:
					$projectSection.val("研发阶段");
					break;
				case now >= appraisalTime && now < prodModelTime:
					$projectSection.val("成果鉴定");
					break;
				case now >= prodModelTime:
					$projectSection.val("生产定型");
					break;
				default:
					alert("");
			}
		});

以上对于IE有问题，IE8不知道的。一下笨拙方法。		
	var now = new Date().valueOf();
			var $projectSection = $('input[name=projectSection]');
			var projectTime = $('#projectTime').val()==''?now+86400:
			    new Date($('#projectTime').val().substring(0, 4), $('#projectTime').val().substring(5, 7)-1, $('#projectTime').val().substring(8, 10)).valueOf();
			var prototypeTime = $('#prototypeTime').val()==''?now+86400:
			    new Date($('#prototypeTime').val().substring(0, 4), $('#prototypeTime').val().substring(5, 7)-1, $('#prototypeTime').val().substring(8, 10)).valueOf();
			var appraisalTime = $('#appraisalTime').val()==''?now+86400:
			    new Date($('#appraisalTime').val().substring(0, 4), $('#appraisalTime').val().substring(5, 7)-1, $('#appraisalTime').val().substring(8, 10)).valueOf();
			var prodModelTime = $('#prodModelTime').val()==''?now+86400:
			    new Date($('#prodModelTime').val().substring(0, 4), $('#prodModelTime').val().substring(5, 7)-1, $('#prodModelTime').val().substring(8, 10)).valueOf();
