jQuery Impromptu(jQuery Dialog插件)(1)--prompt user input in a fashionable way

官方网站:http://trentrichardson.com/Impromptu/index.php

jQuery Impromptu不仅仅只是取代了“alert,prompt,confirm”,它还允许在控件里创建表单,哈!这是一个提示用户输入的很时髦方式。

基本用法:

$.prompt( msg , options )

msg:提示信息的内容可以是一个字符串,或者是一个“states”对象,如果是“states”对象则有以下的属性:

var statesdemo = { 
      state0: {
            html:
'test 1.<br />test 1..<br />test 1',//String,HTML OR TEXT
            buttons: { Cancel: false, Next: true },//按钮的key/value散列表,默认值是{Ok:true}
            focus: 1,//哪个按钮载入时取得焦点,默认值为:0
            submit:function(v,m,f){ 
            
//当这个提示框被提交时调用的函数,默认为:function(){ return true; } 
            //v-点击的按钮的值,在这里是(true/false),m-返回消息框的jQ匹配集,形如$("div"),f-提交的表单
                  if(!v) return true;
                  
else
                        $.ImpromptuGoToState(
'state1');//state转换函数
                  return false
            }
      },
      state1: {
            html:
'test 2',
            buttons: { Back: 
-1, Exit: 0 },
            focus: 
1,
            submit:
function(v,m,f){ 
                  
if(v==0) jQuery.ImpromptuClose()
                  
else if(v=-1)
                        $.ImpromptuGoToState(
'state0');
                  
return false
            }
      }
};

$.prompt(statesdemo); 

 如果msg仅仅是一串字符串则有以下参数:

options

loaded
A function to be called when the prompt is fully loaded Default: function(){}
submit
A function to be called when the prompt is submitted. Default: function(){ return true; }
callback
A function to be called when the prompt is submitted and removed. Default: function(){}
buttons
An object containing the text and values of each button the user may click. Default: { Ok : true }
prefix
A prefix to be used for all css classes and html object id's. Default: 'jqi'
focus
Index of the button to focus(0,1,2..). Default: 0
zIndex //设置css的z-index属性是999,让它在最上一层,避免被覆盖
zIndex to apply to the prompt. Default: 999
useiframe
Will use an iframe for the overlay in IE6 to cover up <select>. Default: false
top //设置弹出层相对于窗口的位置
Distance from the top of the screen the prompt will be Default: 15%
opacity //改变透明度
The prefered opacity of the transparent layer placed over the container. Default: 0.6
overlayspeed
The prefered speed of the fadeIn and fadeOut of the overlay ("slow", "fast", number) Default: "slow"
promptspeed //改变速度$.prompt('Example 6',{promptspeed:'fast',show:'slideDown'});
The prefered opacity of the showing of the prompt ("slow", "fast", number). Default: "fast"
show //显示方式
Name of the jQuery method to animate the entrance of the prompt("show","fadeIn","slideDown"). Default: "fadeIn"
persistent
If the prompt should close when the fade is clicked (true doesn't close). Default: true
调用格式:
$.prompt('Example 4',{ buttons: { Ok: true, Cancel: false }, focus: 1 });
增加一个额外的按钮:
$.prompt('Example 2',{ buttons: { Ok: true, Cancel: false } });
 
改变引用css的前缀:
$.prompt('Example 5',{ prefix: 'impromptu' });

使用回调函数:
function mycallbackfunc(v,m,f){
      $.prompt('i clicked ' + v);
}
$.prompt('Example 8',{ callback: mycallbackfunc });
使用submit function,通过返回false阻止提示框关闭:
var txt = 'Try submitting an empty field:<br />
      <input type="text" id="alertName" 
      name="myname" value="" />
';

function mysubmitfunc(v,m,f){
      an 
= m.children('#alertName');
      
if(f.alertName == ""){
            an.css(
"border","solid #ff0000 1px");
            
return false;
      }
      
return true;
}

$.prompt(txt,{
      submit: mysubmitfunc,
      buttons: { Ok:
true }
});


jQuery Corner Plugin搭配使用使提示框产生圆角:
$.prompt('Example 11',{prefix:'impromptu'}).children('#impromptu').corner();

设置默认值:
$.SetImpromptuDefaults({
      prefix: 'myPrompt',
      show: 'slideDown'
});
