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--; }
