/*//1.设置点击事件,点击软件图标,弹出手机
var tubaio=document.getElementById("tubiao");//获取启动手机按钮图标对象
var jisuanqi=document.getElementById("jisuanqi");//获取手机界面对象
tubaio.onclick=function(){
jisuanqi.style.cssText="display: block";//解除手机桌面隐藏
}*/
//1.(01)(JQuery编写打开关闭手机计算器框设置)
$("#tubiao").click(function(){
if ($("#jisuanqi").css("display")=="none"){
$("#jisuanqi").show();
} else{
$("#jisuanqi").hide();
}
});
//2.设置时间显示,自动更新时间
function show_time() {
//获取时间栏内容
var shijian=document.getElementById("shijian");
//获取当前时间
var dateTime=new Date().toLocaleString();
//用当前时间替换div内容
shijian.innerHTML=dateTime;
}
show_time();//先手动调show_time方法
window.setInterval("show_time()",1000);//编写定时器,每1000ms调用一次show_time方法
//3.设置手机计算器点击事件,击软件图标,弹出计算器
var jipian=document.getElementById("jipian");//获取手机启动计算器按钮图标id
var jizhuomian=document.getElementById("jizhuomian");//获取计算器桌面id
jipian.onclick=function(){
jizhuomian.style.cssText="display: block";//解除计算器界面隐藏
}

shijian.style.cssText="display: block";//解除手机时间栏隐藏
zhuomian.style.cssText="display: block";//解除手机桌面栏隐藏
}*/
//5.锁屏操作(利用JQuery写方代码)
//点击手机主菜单按钮:
//(1)当display属性值为none时,调用show()方法 展示手机桌面(解除锁屏)
//(2)当display属性值为block时,调用hide()方法隐藏手机桌面(启动锁屏)

//6.设置隐藏提示框(点击提示框,提示框消失)

if ($("#tishikuang").css("display")=="block"){

//计算器处理小数点的问题
if(this.innerHTML == ".") {
//判断这个numValue1 里面有没有点,并且点不能出现在首位
if(numValue1.indexOf(".") == -1 && numValue1.length >= 1) {
//我们点击了数字显示到文本框中
numValue1 += this.innerHTML;
//展示一下
show_number1.value = numValue1;
}
} else {
//我们点击了数字显示到文本框中
numValue1 += this.innerHTML;
//展示一下输入数字到文本框中
show_number1.value = numValue1 * 1;//去除首尾的无效0
}
}
}
//(3)给所有的操作符号 设置点击事件
var opers = document.getElementsByClassName("yunsuanfu");
for(var i = 0; i < opers.length; i++) {
opers[i].onclick = function() {
//在这里处理四则
if(numValue2 == "") {
//当你点击了操作符之后,我们把numValue1,给numValue2来保存
//把numValue1清空掉 然后让他去接收第二个数字
numValue2 = numValue1;
numValue1 = "";
//保存操作符
czf = this.innerHTML;
show_yunsuuan.value = czf;//去除首尾的无效0
show_number2.value=numValue1;
} else {
//处理四则运算的逻辑:把前两次个数的运算结果算出来,再赋值给numValue2
//然后把numValue1 清空,准备接收下一个数字
funResult();
//保存操作符
czf = this.innerHTML;
show_yunsuuan.value = czf;//去除首尾的无效0
show_number2.value=numValue1;
}
}
}
//(4)处理清空键的逻辑
clean.onclick = function() {
//把所有的设置归置为初始状态
numValue1 = "";
numValue2 = "";
czf = "";
show_number1.value = "0";
show_number2.value = "0";
show_yunsuuan.value = "";
show_jieguo.value="";
}
//(5)处理退格键
del.onclick = function() {
if(numValue1.length > 1) {
numValue1 = numValue1.substring(0, numValue1.length - 1);
show_number2.value = numValue1;
show_number1.value = numValue2;
} else if(numValue1.length == 1) {
numValue1 = "";
numValue2 = "";
czf = "";
show_number1.value = "0";
show_number2.value = "0";
show_yunsuuan.value = "";
show_jieguo.value="";
}
}
//(6)处理等号逻辑
denghao.onclick = function() {
funResult();
}
function funResult() {
if(numValue1 != "") {
var one = Number(numValue2);
var two = Number(numValue1);
var jg = "0";
switch(czf) {
case "+":
jg = one + two;
break;
case "-":
jg = one - two;
break;
case "*":
jg = one * two;
break;
case "/": //处理除数为0
if(two == 0) {
alert("除数不能为0");
numValue1 = "";
numValue2 = "";
czf = "";
show_number.value = "0";
} else {
jg = one / two;
}
break;
}
var n = new Number(jg);
var finalR = n.toFixed(4);
numValue2 = finalR; //把结果再赋值给numValue2
numValue1 = ""; //清空numValue1
//去掉首尾无效的0 给值*1 即可
show_jieguo.value =numValue2 * 1;
}
}
