微信端没有纯数字键盘，用html5写了一个模仿ios输入支付密码键盘效果
keyboard.js
var _keyboard = {};
$(document).ready(function(){
_keyboard.bindKey();
_keyboard.close();
});
_keyboard.num = 0;
/**
* 给键盘绑定事件
*/
_keyboard.bindKey=function(){
$("#keyId").on("tap","li",function(){
var jthat = $(this);
var numVal = jthat.attr("val");
var inputVal = $("#contentId").val();
if(numVal == -1){ //删除数值
_keyboard.delChar();
}else{ //添加数值
_keyboard.addChar(numVal);
}
});
}
/**
* 添加字符
* @param {Object} numVal 按键的num
* @param {Object} inputVal input内容
*/
_keyboard.addChar=function(numVal){
// console.log(numVal);
if(numVal == "."){
return ;
}
if($("#contentId").find("input").eq(5).val() == ""){
$("#contentId").find("input").eq(_keyboard.num).val(numVal);
}
if(_keyboard.num < 5){
_keyboard.num++;
}
}
_keyboard.close = function(){
$("#keyboardClose").on("click",function(){
$("#contentId").hide();

$("#keyboardbackground").hide();
});

/**

*/
_keyboard.delChar=function(){
$("#contentId").find("input").eq(_keyboard.num).val("");
if(_keyboard.num == 0){return }
