本文實例講述了jQuery實現html雙向綁定功能。分享給大家供大家參考，具體如下：
<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><script type="text/javascript" src="jquery-1.9.1.js"></script><script>var user = new User('123');$(function(){user.set( "name", "99" );}); function GetData() { alert(user.attributes.name); }function DataBinder( object_id ) { var pubSub = jQuery({}); var data_attr = "bind-" + object_id, message = object_id + ":change"; jQuery( document ).on( "change", "[data-" + data_attr + "]", function( evt ) { var $input = jQuery( this ); pubSub.trigger( message, [ $input.data( data_attr ), $input.val() ] ); }); pubSub.on( message, function( evt, prop_name, new_val ) { jQuery( "[data-" + data_attr + "=" + prop_name + "]" ).each( function() { var $bound = jQuery( this ); if ( $bound.is("input, textarea, select") ) { $bound.val( new_val ); } else { $bound.html( new_val ); } }); }); return pubSub;}function User( uid ) { var binder = new DataBinder( uid ), user = { attributes: {}, set: function( attr_name, val ) { this.attributes[ attr_name ] = val; binder.trigger( uid + ":change", [ attr_name, val, this ] ); }, get: function( attr_name ) { return this.attributes[ attr_name ]; }, _binder: binder }; binder.on( uid + ":change", function( evt, attr_name, new_val, initiator ) { if ( initiator !== user ) { user.set( attr_name, new_val ); } }); return user; }</script></head><body><input type="text" data-bind-123="name" /><br/><input type="button" onclick="GetData();" value="獲取數據"></div></body></html>更多關于jQuery相關內容感興趣的讀者可查看本站專題：《jQuery常見事件用法與技巧總結》、《jQuery常用插件及用法總結》、《jQuery操作json數據技巧匯總》、《jQuery擴展技巧總結》、《jQuery常見經典特效匯總》、《jQuery動畫與特效用法總結》及《jquery選擇器用法總結》
