前言：码奴生来只知道前进
很多时候在用户输入邮箱的时候 大多是使用快捷方式
效果图如下

var emailArry = [
"@qq.com",
"@sina.com",
"@163.com",
"@126.com",

"@gmail.com",
"@sohu.com"
];
$("#email").bind('input propertychange',function(){
var key = $("#email").val();
if(key.indexOf("@") != -1){
key = key.slice(0,key.indexOf("@"));
}
var mailBoxLen = emailArry.length;
var table = "";
for(var i=0; i<mailBoxLen; i++){
table += '<option value="'+ key + emailArry[i] +'"></option>';
}
$("#input_list").html(table);
});
</script>
