//验证输入框
function ValidateCompent(input){
  var _input = $(input).clone(true);
  _input.css("height",$(input).css("height"));
  _input.css("width", $(input).css("width"));
  var border =_input.css("border"); 
  this.successIconClass = "icon-tick";//验证通过时的样式
  this.validate = false;
  this.faileIconClass = "icon-times";//验证失败时的样式
  var $validateRoot = $('
');
  var $tooltip = $validateRoot.children(".validate-v1-tooltip");
  var $input = _input;
  if($input != undefined){
    var maxWidth = $input.css("width");
    var maxHeight = $input.css("height");
    $validateRoot.css("display","inline");
    $validateRoot.css("position","relative");
    $validateRoot.css("width",maxWidth);
    $validateRoot.css("height",maxHeight);
    $tooltip.css("width",maxWidth);
    $tooltip.css("padding","0px 5px");
    $tooltip.css("position","absolute");
    $tooltip.css("top","0px");
    $tooltip.css("z-index","999999");
    $tooltip.css("background-color","white");
    $tooltip.css("border","solid 1px rgb(188,188,188)");
    $tooltip.css("left",parseInt(maxWidth) + 10+"px");
    $tooltip.hide();
    var validateOption = $input.attr("data-vali-option");
    if(validateOption != undefined){
      validateOption = JSON.parse(validateOption);
      var that = this;
      var regvali = new Array();
      $tooltip.hide();
      if(validateOption.length == 0){
        return;
      }
      for(var i = 0; i
'); var $icon = dom.children(".vticon"); var $message = dom.children(".vmessage"); $message.css("line-height","28px"); $message.css("padding","5px 5px"); $message.css("padding-right","10px"); $message.css("word-break","break-all"); $message.css("word-wrap","break-word"); $message.css("font-size","14px"); $message.css("position","relative"); $message.css("z-index","999999"); this.setIconClass = function(iconClass){ $icon.removeClass(); $icon.addClass("vticon"); $icon.addClass(iconClass); } this.getIcon = function(){ return $icon; } this.setMessageText = function(_message){ $message.html(_message); } this.getMessageText = function(){ return $message; } this.setIconClass(iconFontClass); this.setMessageText(message); this.dom = dom; } $validateRoot.insertAfter($(input)); $(input).remove(); }

以下是HTML代码

使用方法如下

$(function(){
  var c = new ValidateCompent("#test");
});

依赖JQuery,

另外附上JQuery textchange事件的代码，textchange代码放在JQuery之后，在使用方法之前。

(function($) {
var testNode = document.createElement("input");
var isInputSupported = "oninput" in testNode &&

var hasInputCapabilities = function(elem) {
  // The HTML5 spec lists many more types than `text` and `password` on
  // which the input event is triggered but none of them exist in IE 8 or
  // 9, so we don't check them here.
