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(); 
			$("#_Wdafy_keyboard").hide(); 
			$("#keyboardbackground").hide();
		});
	}
	/**
	 * 删除字符
	 * @param {Object} inputVal  当前input的val
	 */
	_keyboard.delChar=function(){	
		$("#contentId").find("input").eq(_keyboard.num).val("");
		if(_keyboard.num == 0){return }
		_keyboard.num--;
		
	}
