[英]Can I minify JavaScript or aspx code in Microsoft Visual Studio 2010
[英]How to pass value from HTML to a ASPX files in Visual Studio 2010
我的HTML文件中包含以下代碼:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script type="text/javascript">
function myFunction() {
debugger;
var checkedvalue = "";
var arrChecks = document.getElementsByName("theCheckbox");
for (i = 0; i < arrChecks.length; i++)
{
// if the current state is checked, unchecked and vice-versa
if (arrChecks[i].checked) {
arrChecks[i].checked = false;
} else {
arrChecks[i].checked = true;
checkedvalue = checkedvalue + " " + arrChecks[i].getAttribute('value');
}
}
document.getElementById("demo").innerHTML = checkedvalue;
}
function makeCheckboxes(str) {
var a = document.getElementById("blah");
var arr = str;
var returnStr = "";
for (i = 0; i < arr.length; i++) {
returnStr += '<input type="checkbox" name="theCheckbox" value="' + arr[i] + '" />' + arr[i];
}
a.innerHTML = returnStr;
}
window.onload = function () {
var arrt = ["test1", "test2", "apple", "samsung", "nokia"];
makeCheckboxes(arrt);
};
</script>
<style type="text/css"></style>
</head>
<body>
<table border="1">
<tr>
<td id="blah"></td>
<td>checkboxes should appear left of here</td>
<button onclick="myFunction()">Click me</button>
</tr>
</table>
<p id="demo"></p>
</body>
</html>
因此,如何將值從單個HTML文件傳遞到ASPX文件,ASPX文件是用於將值從單個HTML文件存儲到數據庫的?
假設用戶選中test1
, test2
和nokia
的復選框,然后單擊Click me
按鈕。 變量samsung
和apple
將被傳輸到ASPX文件並存儲為變量,以后可以存儲到數據庫中。
對於您的信息,我不希望使用URL將變量信息傳遞給aspx文件。 (例如, http : //website.com/info.aspx? var = samsung&var =apple )
這是html頁面的示例,將變量發送到aspx頁面,在aspx頁面的cs文件中,您可以正常使用來自html頁面的變量
在aspx的cs代碼中
protected void Page_Load(object sender, EventArgs e)
{
string s = Request.Form.Get("param1");
}
在HTML中
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Untitled Page</title>
<script src="jquery-1.7.1.min.js" type="text/javascript"></script>
<script src="jquery.mobile-1.1.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
myFunction = function() {
var txtValue = document.getElementById("mytxt" ).value;
try {
$.ajax({
type: "POST",
url: "Default.aspx",
data:"param1=" + txtValue ,
contentType: "application/x-www-form-urlencoded; charset=utf-8",
dataType: "html",
success: function(msg) {
},
error: function(xhr, status, error) {
alert('Error');
}
});
}
catch(e)
{
alert(e);
}
};
</script>
</head>
<body>
<table >
<tr>
<td id="blah">
<input id="mytxt" type="text" />
</td>
</tr>
<tr>
<td>
<input type="button" value="Redirect" onclick="myFunction()" />
</td>
</tr>
</table>
</body>
</html>
在您的HTML文件中制作一個Javascript標記,並將此代碼放在上面
$.ajax({
type: "POST",
url: "../YourAspxpath/yourAspxFile.aspx",
data: { param1: "value", param2: "value" },
contentType: "application/x-www-form-urlencoded; charset=utf-8",
dataType: "html",
success: function (msg) {
//do what ever you wnt here in case of success
},
error: function (xhr, status, error) {
alert('Error');
}
});
