今天将需要chat集成到客户的网站上去,注册用户链接登录这个网站后点击实现网站直接登录chat向上。我不停chat原来的登录界面,采纳JS当页面跳转技术,随着时间的推移自己主动填写表格。自己主动提交表单,从而实现站点用户无需再次登录就可以进入chat。详细代码实现例如以下
JS代码
<script> //取得cookie值 function getCookie(name){ var arr,reg=new RegExp("(^| )"+name+"=([^;]*)(;|$)"); if(arr=document.cookie.match(reg)){ return unescape(arr[2]); }else{ return null; } } //表单自己主动提交函数 function tijiao(){ function sub(){ var a = document.getElementById('loginForm'); a.elements[2].value = getCookie('username'); a.elements[3].value = getCookie('username'); var opts = document.getElementById("channelField"); opts[1].selected = 'selected'; opts[0].selected = ''; a.submit(); } setTimeout(sub,0);//以毫秒为单位的.1000代表一秒钟.依据你须要改动这个时间. } //点击button提交表单 function clickbutton(obj){ obj.onclick = function(){ obj.submit(); } } </script>
HTML代码
<form id="loginForm" name="loginForm" action="[LOGIN_URL/]" method="post" enctype="application/x-www-form-urlencoded"> <div id="loginFormContainer" style="margin:0px;padding-bottom: 10px;"> <input type="hidden" name="login" id="loginField" value="login"/> <input type="hidden" name="redirect" id="redirectField" value="[REDIRECT_URL/]"/> <div><label for="userNameField">[LANG]userName[/LANG]:</label> <input type="text" name="userName" id="userNameField" maxlength="[USER_NAME_MAX_LENGTH/]"/></div><br /> <div><label for="passwordField">[LANG]password[/LANG]*:</label> <input type="password" name="password" id="passwordField"/><span style="margin-left:4px; color: #339900;">默认是您的username</span></div><br /> <div><label for="channelField">[LANG]channel[/LANG]:</label> <select name="channelName" id="channelField">[CHANNEL_OPTIONS/]</select></div><br /> <div><label for="languageSelection">[LANG]language[/LANG]:</label> <select id="languageSelection" name="lang" onchange="ajaxChat.switchLanguage(this.value);">[LANGUAGE_OPTIONS/]</select></div><br /> <!-- <div><input type="submit" name="submit" style=" 240px;height: 50px;background: url(../chat/img/bglogin2.png);background-repeat: no-repeat;border: 0px;" id="loginButton" value=""/></div> --> <div><button name="subButton" onclick="clickbutton(this);" style=" 240px;height: 50px;background: url(../chat/img/bglogin2.png);background-repeat: no-repeat;border: 0px;" id="loginButton" value=""></button></div> </div> </form>
PS:
1. 要在body中增加onload="tijiao();"
2. 另外表单的提交button(submit)须要隐去。不然会和js的submit()方法冲突,这里採用button提交,避免在自己主动登录失败时没这里提交button
