validator for dynamically added fields

[Selva kumar, modificado hace 7 años.]

I have a field with the name "material" in my form. This field gets added dynamically in the form on button click. On intial render of the page, the field wont be available in DOm. After button click, i will add a input with the name into the form.

What i need is to add a "required" validator and a custom validator to the new added field.
I tried the below codefor the "required" validator.

var myFormValidator = Liferay.Form.get('<portlet:namespace />materialForm').formValidator;
var myFld = Y.one('#<portlet:namespace/>material');
var err= {};
err.required = 'Material is mandatory';
myFormValidator .addFieldError(myFld , err );

But the above doesnt work. It doesnt bind the the error to the validator.

Try this

this.formValidator = new Y.FormValidator(
					  {
						boundingBox: Y.one("#" + this.get("formId")),
						validateOnInput: true,
						validateOnBlur: false,
						strings:  this.get("STRINGS"),
					  }
					);

	var rules =  "({";
	var rule = "";
		//Add your custom rules
		if (field.rule.type != ""){
			rules += '_86_custom_'+	
				field.jsName + ': {'+
				field.rule.type + ': true,';
			if (field.rule.range != "")
				rules += 'range:' + field.rule.range + ',';
			if (field.rule.rangeLength != "")
				rules += 'rangeLength:' + field.rule.rangeLength + ',';
			rules += '},';
		}

rules += "})";
oSelf.formValidator.set("rules", eval(rules));
oSelf.formValidator.validate();

Hope it helps

For Default validator

var frmValidator = Liferay.Form.get('<portlet:namespace />materialForm').formValidator;
frmValidator.get('rules')['<portlet:namespace />materialId'] = {required: true, custom: false};

For Custom validator

AUI().use('aui-form-validator', function(A) {
var _validatorConfig = A.config.FormValidator;
if(!_validatorConfig.RULES.custom_id){
A.mix(_validatorConfig.RULES, {
custom_id: function(val, fieldNode, ruleValue) {
if (val < 100) {
return true;
}
return false;
},
}, true);
A.mix(_validatorConfig.STRINGS, {
custom_id: "Material Id is invalid",
}, true);
}
var frmValidator = Liferay.Form.get('<portlet:namespace />materialForm').formValidator;
frmValidator.get('rules')['<portlet:namespace />materialId'] = {custom_id: true, custom: true};
});

I may be better to have the field always in the DOM, but hidden, and to dynamically required the field when it's displayed.

...
required: function() {
    return // check if input displayed
}
...
