1、使用div+css布局出win7計算器界面（純div+css）
不要找別人要代碼，自動動手，把css：浮動、定位搞懂了做你這個很簡單。
計算器上面就是一個框框加幾排按鈕..
2、html 如何設計帶小數的計算器
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>無標題文檔</title>
<style type="text/css">
input {
height:32px;
width:45px;
}
</style>
</head>
<body>
<table>
<tr>
<td scope="col"><input type="button" value="復位" id = "c"></td>
<td scope="col"><input type="text" value="" id="msg" style="width:155px;"></td>
</tr>
<tr>
<td scope="col">結果:</th>
<td scope="col"><input type="text" value="" id="r" style="width:155px;"></td>
</tr>
</table>
<table width="16%" border="0">
<tr style="text-align:left;">
<th width="25%" scope="col"><input type="button" value="1"></th>
<th width="25%" scope="col"><input type="button" value="2"></th>
<th width="25%" scope="col"><input type="button" value="3"></th>
<th width="25%" scope="col"><input type="button" value="+"></th>
</tr>
<tr>
<td><input type="button" value="4"></td>
<td><input type="button" value="5"></td>
<td><input type="button" value="6"></td>
<td><input type="button" value="-"></td>
</tr>
<tr>
<td><input type="button" value="7"></td>
<td><input type="button" value="8"></td>
<td><input type="button" value="9"></td>
<td><input type="button" value="*"></td>
</tr>
<tr>
<td><input type="button" value="0"></td>
<td><input type="button" value="."></td>
<td><input type="button" value="=" id="s"></td>
<td><input type="button" value="/"></td>
</tr>
</table>
<script type="text/javascript">
var x=document.getElementsByTagName("input");
for(var f1 in x){
x[f1].onclick = function(){
m(this.value)
}
}
document.getElementById("s").onclick = function(){
var ss = document.getElementById("msg").value;
document.getElementById("r").value = eval(ss);
};
document.getElementById("c").onclick = function(){
document.getElementById("msg").value="";
document.getElementById("r").value="";
}
function m(s){
var ss = document.getElementById("msg").value;
ss = ss || "";
ss = ""+ss + s;
document.getElementById("msg").value= ss;
}
</script>
</body>
</html>
3、網頁中如何做計算器
輸入如下代碼就可以了
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>Calculate</title>
<script language="VBSCRIPT">
Function Show(m)
If (Myform.Expression.Value = "" AND InStr(". + - * / ",m)) Then
Myform.Expression.Value = ""
ElseIf (InStr("+ - * / . ",Right(Myform.Expression.Value,1)) And InStr("+ - * / ",m)) Then
ElseIf (m = ".") Then
If (InStr("+ - * / . ",Right(Myform.Expression.Value,1))) Then
ElseIf ((InstrRev(Myform.Expression.Value,".") > InstrRev(Myform.Expression.Value,"+")) And (InstrRev(Myform.Expression.Value,".") > InstrRev(Myform.Expression.Value,"-")) And (InstrRev(Myform.Expression.Value,".") > InstrRev(Myform.Expression.Value,"*")) And (InstrRev(Myform.Expression.Value,".") > InstrRev(Myform.Expression.Value,"/"))) Then
Else
Myform.Expression.Value = Myform.Expression.Value + m
End If
Else
Myform.Expression.Value = Myform.Expression.Value + m
END If
End Function
Function Sqrt()
If (Myform.Expression.Value = "") Then
Myform.Expression.Value = ""
ElseIf (InStr(". + - * / ",Right(Myform.Expression.Value,1))) Then
Else
Myform.Expression.Value = Eval(Myform.Expression.Value)^2
End If
End Function
Function Result()
If (Myform.Expression.Value = "") Then
Myform.Expression.Value = ""
ElseIf (InStr(". + - * / ",Right(Myform.Expression.Value,1))) Then
Else
Myform.Expression.Value = Eval(Myform.Expression.Value)
End If
End Function
Function Clean()
Myform.Expression.Value = ""
End Function
</script>

4、如何用運用html和css相關技術，設計一個網頁在線計算器的界面
html+css只是靜態樣式。而涉及到計算方面，得再加js就能實現了。
5、網頁設計與製作設計一個頁面,實現一個四則計算器
這個代碼其實網上有很多現成的，而且做有CSS布局各種形式的都有，自己多花點時間搜索下就可以找到 。
6、html網頁計算器代碼怎麼寫？
html網頁計算器代碼編寫過程如下：
7、用css js做一個網頁版的計算器，要有加減乘除運算，和歸零刪除鍵
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>計數器</title>
</head>
<body>
<input type="text" name="text" id="pre" onblur="validate(this.value);">
<select id="operator">
<option value="+">+</option>
<option value="-">-</option>
<option value="*">*</option>
<option value="/">/</option>
</select>
<input type="text" name="text" id="next" onblur="validate(this.value);">
<span>=</span>
<input type="text" id="result" readonly="true">
<input type="button" id="btn" value="提交" onclick="calculator();">
<script>
function validate(str){
var reg = /^\d+$/;
if (!reg.test(str)) {
alert("請輸入數字");
}
}
function calculator(){
var pre=document.getElementById("pre").value;
var next=document.getElementById("next").value;
var opra=document.getElementById("operator").value;
var result=0;
switch(opra) {
case "+":
result=parseInt(pre)+parseInt(next);
break;
case "-":
result=parseInt(pre)-parseInt(next);
break;
case "*":
result=parseInt(pre)*parseInt(next);
break;
case "/":
if(parseInt(next)!=0){
result=parseInt(pre)/parseInt(next);
}
else{
alert("除數不能為0");
return;
}
break;
default:
break;
}
document.getElementById("result").value=result;
}
</script>
</body>
</html>
8、如何用css js製作計算器？
源代碼如下：
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>js加減乘除計算器代碼</title>
<style>
