我有一个带有完美工作的验证脚本的表单。但是,我希望表单跳转到不验证或显示错误消息中的字段名称的字段。
我用来验证的代码是:
else
{
var valid = document.formvalidator.isValid(f);
}
if (flag == 0 || valid == true) {
f.check.value = '<?php echo JUtility::getToken(); ?>';//send token
}
else {
alert('There was an error with the fields..');
return false;
}
return true;
如何获得警报以命名需要正确填写的字段或跳转到特定字段?

你好,
感谢您到目前为止的帮助。我对 JS 很陌生。该表单位于 Joomla 的一个组件中。
验证表单的完整功能是
function validateForm(f){
var browser = navigator.appName;
if (browser == "Microsoft Internet Explorer"){
var flag = 0;
for (var i=0;i < f.elements.length; i++) {
el = f.elements[i];
if ($(el).hasClass('required')) {
var idz= $(el).getProperty('id');
if(document.getElementById(idz)){
if (!document.getElementById(idz).value) {
document.formvalidator.handleResponse(false, el);
flag = flag + 1;
}
}
}
}
}
else {
var valid = document.formvalidator.isValid(f);
}
if(flag == 0 || valid == true){
f.check.value='<?php echo JUtility::getToken(); ?>';//send token
}
else {
alert('<?php echo JText::_('JBJOBS_FIEDS_HIGHLIGHTED_RED_COMPULSORY'); ?>');
return false;
}
return true;
}
外部js文件:
var JFormValidator = new Class(
{
initialize : function() {
this.handlers = Object();
this.custom = Object();
this.setHandler("username", function(b) {
regex = new RegExp("[<|>|\"|'|%|;|(|)|&]", "i");
return !regex.test(b)
});
this.setHandler("password", function(b) {
regex = /^\S[\S ]{2,98}\S$/;
return regex.test(b)
});
this.setHandler('passverify',
function (value) {
return ($('password').value == value);
}
); // added March 2011
this.setHandler("numeric", function(b) {
regex = /^(\d|-)?(\d|,)*\.?\d*$/;
return regex.test(b)
});
this
.setHandler(
"email",
function(b) {
regex = /^[a-zA-Z0-9._-]+(\+[a-zA-Z0-9._-]+)*@([a-zA-Z0-9.-]+\.)+[a-zA-Z0-9.-]{2,4}$/;
return regex.test(b)
});
var a = $$("form.form-validate");
a.each(function(b) {
this.attachToForm(b)

},
setHandler : function(b, c, a) {
a = (a == "") ? true : a;
this.handlers[b] = {

if (document.id(c.get("id") + a).checked) {
break
}
} else {
this.handleResponse(false, c);
return false
}
}
} else {
if (!(c.get("value"))) {
this.handleResponse(false, c);
return false
}
}
}
var b = (c.className && c.className
.search(/validate-([a-zA-Z0-9\_\-]+)/) != -1) ? c.className
.match(/validate-([a-zA-Z0-9\_\-]+)/)[1]

if (b == "") {
this.handleResponse(true, c);
return true
}
if ((b) && (b != "none") && (this.handlers[b])
&& c.get("value")) {
if (this.handlers[b].exec(c.get("value")) != true) {
this.handleResponse(false, c);
return false
}
}
this.handleResponse(true, c);
return true
},
isValid : function(c) {
var b = true;
var d = c.getElements("fieldset").concat($A(c.elements));
for ( var a = 0; a < d.length; a++) {
if (this.validate(d[a]) == false) {
b = false
}
}
new Hash(this.custom).each(function(e) {
if (e.exec() != true) {
b = false
}
});
return b
},
handleResponse : function(b, a) {
if (!(a.labelref)) {
var c = $$("label");
c.each(function(d) {
if (d.get("for") == a.get("id")) {
a.labelref = d
}
})
}
if (b == false) {
a.addClass("invalid");
a.set("aria-invalid", "true");
if (a.labelref) {
document.id(a.labelref).addClass("invalid");
document.id(a.labelref).set("aria-invalid", "true");
}
} else {
a.removeClass("invalid");
a.set("aria-invalid", "false");
if (a.labelref) {
document.id(a.labelref).removeClass("invalid");
document.id(a.labelref).set("aria-invalid", "false");
}
}
}
});
document.formvalidator = null;
window.addEvent("domready", function() {
document.formvalidator = new JFormValidator()
});
正如你们中的一些人在下面回答的那样,我将在哪里编辑代码?
