Using RSV jQuery Validation from here .
Really stuck at one place. I wrote custom error handler for this plug-in (read documentation, it's allowed), now it shows errors, and focuses at exact fields one by one, then at the end of validation my custom handler return (errorInfo.length == 0) ? true : false;
return (errorInfo.length == 0) ? true : false;
returns true if there is no error. The problem is, after this rsv directly send form data to PHP. But I want to fire Ajax function after successfull validaton. I wrote another function wellDone()
for "on complete" event seems plugin doesn't fire oncomplete function at all. Please help me to fix that problem.
$(document).ready(function() {
$("#signup_form").RSV({
onCompleteHandler: wellDone,
customErrorHandler: errorHandler,
rules: signup_rules
});
});
function errorHandler(f, errorInfo)
{
for (var i=0; i<errorInfo.length; i++)
{
// errorInfo[i][0] contains the form field node that just failed the validation, e.g.
errorInfo[i][0].focus();
// errorInfo[i][1] contains the error string to display for this failed field, e.g.
$.notifyBar({
cls: "error",
html: errorInfo[i][1]
});
}
return (errorInfo.length == 0) ? true : false;
}
function wellDone(){
signUp();
}
var signup_rules = [
<some validation rules>...
]
If you use a customErrorHandler
, then in fact the onCompleteHandler
will never be called. It is assumed you call it yourself at the end of your customErrorHandler
when errorInfo.length == 0
.
可能您应该将从customErrorHandler函数返回的true或false值缓存在一个变量中(所有执行ajax调用的函数都可以使用该变量),并使用它来确定是否触发ajax调用。
Your customErrorHanlder should always return "false", but not " balabala ? true : false"
This is for people that are comfortable with javascript and who need a little more control over how the errors are presented. It lets you define your own custom function that gets passed the list of errors that occur on a form submit. Here's a simple example that alerts each error in turn. Note: the two function parameters MUST be set in order to be passed the error information properly.
customErrorHandler:
$(document).ready(function() {
$("#demo_form1").RSV({
customErrorHandler: myReturnFunction,
rules: [
// ...
]
}); });
/**
* @param f the form node
* @param errorInfo an array of arrays. Each sub-array has two elements: the field node and the error message.
*/
function myReturnFunction(f, errorInfo) {
for (var i=0; i<errorInfo.length; i++)
{
// errorInfo[i][0] contains the form field node that just failed the validation, e.g.
errorInfo[i][0].focus();
errorInfo[i][0].style.color = "red";
// errorInfo[i][1] contains the error string to display for this failed field, e.g.
alert(errorInfo[i][1]);
}
return false; // always return false! Otherwise the form will be submitted**
}
see the last line of code and its comment? ALWAYS return false :-)
