The following is the js Code (it is not elegant when binding objects. I hope you can give me some advice !) Copy codeThe Code is as follows: function validator (obj, option) {// verify the object
Var self = this;
If (! (Self instanceof validator ))
Return new validator (obj, option );
Self. source = {'mobile': '^ (13 | 14 | 15 | 18) [0-9] {9} $', 'postcode ': '^ \ d {6} $', 'integer': '^ -? \ D * $ ', 'email': '^ \ w + (-\ w +) | (\\. \ w +) * \ @ [A-Za-z0-9] + ((\\. |-) [A-Za-z0-9] + )*\\. [A-Za-z0-9] + $ ', 'url':' ^ http [s]? : \/([\ W-] + \.) + [\ w-] + ([\ w -./? % & =] *)? $ '};
For (var I in self. source ){
If (I = option. type)
Self. type = self. source [I];
}
Self. tag = 2;
Self. input = obj;
Self. options = option;
Self. tip = document. getElementById (self. options. tips );
Self. text = self. tip. innerHTML;
Self. init (obj );
}
Validator. prototype. init = function (o ){
Var self = this;
AddEvent (o, 'focal ', function (){
Self. focus ();
});
AddEvent (o, 'blur', function (){
Self. valid ();
});
}
Validator. prototype. valid = function (){
Var self = this;
Var reg = self. options. reg | self. type;
If (new RegExp (reg). test (self. input. value. replace (/\ s/ig ,''))){
Self. tip. className = 'validator _ oncorrect ';
Self. tip. innerHTML = 'entered correctly ';
Self. tag = 1;
} Else {
Self. tip. className = 'validator _ onerror ';
Self. tip. innerHTML = 'sorry, the content you entered does not comply with the rules! ';
Self. tag = 0;
}
}
Validator. prototype. focus = function (){
This. tip. className = 'validator _ onfocus ';
This. tip. innerHTML = this. text;
}
Function addEvent (el, type, fn) {// bind an event
If (el. attachEvent ){
El ['E' + type + fn] = fn; // copy element references under IE to point this to the el object instead of the window
El [type + fn] = function () {el ['E' + type + fn] (window. event );}
El. attachEvent ('on' + type, el [type + fn]);
} Else
El. addEventListener (type, fn, false );
}
// Page call Method
Var inputs = document. getElementsByTagName ('input'); // The method here is strange, not elegant enough, and no optimization method is found.
Var arr = [];
Arr [0] = validator (inputs [0], {type: 'postcode', tips: 'm1 '});
Arr [1] = validator (inputs [1], {type: 'url', tips: 'm2 '});
Arr [2] = validator (inputs [2], {type: 'email ', tips: 'm3 '});
Arr [3] = validator (inputs [3], {type: 'mobile', tips: 'm4 '});
Arr [4] = validator (inputs [4], {type: 'integer', tips: 'm5', reg: '^ -? \ D * $ '});
Function submitForm () {// submit a form filter
Var l = arr. length;
For (var I in arr ){
If (arr [I]. tag = 1)
L --;
Else if (arr [I]. tag = 2 ){
Arr [I]. valid ();
}
}
If (l! = 0) return false;
}
