这个插件支持大部分的浏览器,但由于有使用到了css3的阴影和圆角样式,所以在IE浏览器下无法看到圆角和阴影效果(万恶的IE)。

普通验证的例子:http://www.position-relative.net/creation/formValidator/
ajax验证的例子:http://www.position-relative.net/creation/formValidator/demoSubmit.html
一:简单说明下使用教程:
引入jquery和插件js、css
- <link rel="stylesheet" href="css/validationEngine.jquery.css" type="text/css" media="screen" charset="utf-8" />
- <script
src="js/jquery.js" type="text/javascript"></script> - <script
src="js/jquery.validationEngine-en.js" type="text/javascript"></script> - <script
src="js/jquery.validationEngine.js" type="text/javascript"></script>
jquery.validationEngine-en.js是语言文件,所有的提示都在这个文件找的到,可以很方便的转成其他语言,同时你也可以在这个文件内定制属于自己的验证规则。
初始化插件
- $(document).ready(function() {
- $("#formID").validationEngine()
- })
验证规则是写在表单元素的class属性内。比如下面:
- <input value="" class="validate[required,custom[noSpecialCaracters],length[0,20],ajax[ajaxUser]]" type="text" name="user" id="user" />
验证规则非常多样,基本上包含了所有的数据类型的验证。
所有的验证规则写在validate[]内,有多种验证,用逗号隔开,这里简要说明下常用的验证规则。
- required:值不可以为空
- length[0,100] :文字允许长度
- confirm[fieldID] :匹配其他的表单元素的值,fieldID就是其他表单元素的id,这个主要用于再次确认密码
- telephone :数据格式要求符合电话格式
- email : 数据格式要求符合email 格式
- onlyNumber :只允许输入数字
- noSpecialCaracters :不允许出现特殊字符
- onlyLetter : 只能是字母
- date :必须符合日期格式YYYY-MM-DD
你还可以在点击提交按钮后才触发验证。
- $("#formID").validationEngine({
- inlineValidation: false,
- success :
false, - failure : function()
{ callFailFunction() } - })
默认的是在鼠标失去焦点后才开始验证,也就是绑定的是blur事件,那如何改变呢?看下面的配置。
- $("#formID").validationEngine({
- validationEventTriggers:"keyup blur",
//will validate on keyup and blur - success :
false, - failure : function()
{ callFailFunction() } - })
validationEventTriggers属性就是修改绑定事件,上面是增加了个keyup,也就是键盘按键起来就触发验证。
修改提示层的位置
- $("#formID").validationEngine({
- promptPosition: "topRight", // OPENNING BOX POSITION, IMPLEMENTED: topLeft, topRight, bottomLeft,
centerRight, bottomRight - success :
false, - failure : function()
{ - })
promptPosition就是控制位置,有5种模式:topLeft, topRight, bottomLeft, centerRight, bottomRight
ajax验证模式
- $("#formID").validationEngine({
-
ajaxSubmit: true, -
ajaxSubmitFile: "ajaxSubmit.php", -
ajaxSubmitMessage: "Thank you, we received your inscription!", -
ajaxSubmitExtraData: "securityCode=38709238423&name=john", -
success : false, -
failure : function() {} - })
这几个参数很好理解。
- ajaxSubmit: true, 提交表单使用ajax提交
- ajaxSubmitFile: “ajaxSubmit.php”, 后台脚本
- ajaxSubmitMessage 成功后显示的信息
- ajaxSubmitExtraData 参数
这里需要对后台脚本返回的数据进行下说明:
返回的数据格式是json。
出现一个错误,产生一个数组,如下:
- $arrayError[0][0] = "#email";
// FIELDID - $arrayError[0][1] = "Your email do not match.. whatever it need to match";
// TEXT ERROR - $arrayError[0][2] = "error";
// BOX COLOR
二:修改过的地方
解决ie6下select遮挡div的办法
jquery.validationEngine.js要修改的地方:
- calculatedPosition.callerTopPosition
+= "px"; -
calculatedPosition.callerleftPosition += "px"; -
calculatedPosition.marginTopSize += "px"; -
//add matychen -
if ( $.browser.msie && /6.0/.test(navigator.userAgent) ) { -
$(divFormError).append('<iframe class="iframe" frameborder="0" scr="javascript:false;"></iframe>'); -
} -
// add matychen -
$(divFormError).css({ -
"top": calculatedPosition.callerTopPosition, -
"left": calculatedPosition.callerleftPosition, -
"marginTop": calculatedPosition.marginTopSize, -
"opacity": 0 -
});
validationEngine.jquery.css里面加入以下代码:
- .iframe
{ -
position: absolute; -
width: expression_r(this.parentNode.offsetWidth+\'px\'); -
height: expression_r(this.parentNode.offsetHeight-32+\'px\'); -
z-index: -1; -
top: expression_r(((parseInt(this.parentNode.currentStyle.borderTopWidth)||0)*-1)+\'px\'); -
left: expression_r(((parseInt(this.parentNode.currentStyle.borderLeftWidth)||0)*-1)+\'px\'); - }

jquery.validationEngine.js要更改的地方:
- success:
function(data){ // GET SUCCESS DATA RETURN JSON -
data = eval_r( "("+data+")"); // GET JSON DATA FROM PHP AND PARSE IT -
ajaxisError = data.jsonValidateReturn[2];//这里官方文档写死了,可以根据自己需求更改。 -
customAjaxRule = data.jsonValidateReturn[1];//这里官方文档写死了,可以根据自己需求更改。 -
ajaxCaller = $("#"+data.jsonValidateReturn[0])[0]; -
fieldId = ajaxCaller; -
ajaxErrorLength = $.validationEngine.ajaxValidArray.length; -
existInarray = false; -
-
if(ajaxisError == "false"){ // DATA FALSE UPDATE PROMPT WITH ERROR; -
-
_checkInArray(false) // Check if ajax validation alreay used on this field -
-
if(!existInarray){ // Add ajax error to stop submit -
$.validationEngine.ajaxValidArray[ajaxErrorLength] = new Array(2); -
$.validationEngine.ajaxValidArray[ajaxErrorLength][0] = fieldId; -
$.validationEngine.ajaxValidArray[ajaxErrorLength][1] = false; -
existInarray = false; -
}
用到了jsonplugin-0.32.jar这个包在附件里面,其他struts的包,自己添加。
