**1.先写好toast的js代码：**

/\*\*  
 \* 模仿android里面的Toast效果，主要是用于在不打断程序正常执行的情况下显示提示数据  
 \* @param config  
 \* @return  
 \*/    
var Toast = function(config)\{    
    this.context = config.context==null?$('body'):config.context;//上下文    
    this.message = config.message;//显示内容    
    this.time = config.time==null?6000:config.time;//持续时间    
    this.left = config.left;//距容器左边的距离    
    this.top = config.top;//距容器上方的距离    
    this.init();    
\}    
var msgEntity;    
Toast.prototype = \{    
    //初始化显示的位置内容等    
    init : function()\{    
        $("\#toastMessage").remove();    
        //设置消息体    
        var msgDIV = new Array();    
        msgDIV.push('<div id="toastMessage">');    
        msgDIV.push('<span>'+this.message+'</span>');    
        msgDIV.push('</div>');    
        msgEntity = $(msgDIV.join('')).appendTo(this.context);    
        //设置消息样式    
        var toastMessageWidth = $('\#toastMessage').innerWidth();  
        var toastMessageHeight = $('\#toastMessage').innerHeight();  
        var windowWidth = $(window).width();  
        var windowHeight = $(window).height();  
        var newWidth = (windowWidth - toastMessageWidth - 80) / 2 + "px";  
        var newHeight = (windowHeight - toastMessageHeight - 80) / 2 + "px";  
        msgEntity.css(\{'left':newWidth,'z-index':'999999','top':newHeight,'background-color':'black','color':'white',  
            'padding':'30px','font-size':'18px','border':'3px solid \#f8c26d'\});    
    \},    
    //显示动画    
    show :function()\{    
        msgEntity.fadeIn(this.time/2);    
        msgEntity.fadeOut(this.time/2);    
    \}          
\}  
function toastFunction(messageString)\{  
    new Toast(\{context:$('body'),message:messageString\}).show();  
    \}

**2.先在你的html主页中添加jquery库和一下样式：**

**3.如何调用：**

toastFunction("成功调用!");
