推荐答案
尝试在body标签上使用onload事件的简单解决方案...
Hi,
Try this simple solution that is using onload event on body tag...
<html>
<head>
<script>
var counter = 0;
function AddFileUpload()
{
var div = document.createElement('DIV');
div.innerHTML = '<input id="file' + counter + '" name = "file' + counter + '" type="file" /><input id="Button' + counter + '" type="button" value="Remove" onclick = "RemoveFileUpload(this)" />';
document.getElementById("FileUploadContainer").appendChild(div);
counter++;
}
function RemoveFileUpload(obj)
{
return false;
}
</script>
</head>
<body onload="AddFileUpload();">
<div id="FileUploadContainer"></div>
<input type="button" value="Add" onclick="AddFileUpload();return false;">
</body>
</html></html>
如果您使用jquery，则可以使用.ready()事件来调用此dom DOM已准备就绪...
If you use jquery you can use .ready() event to call this whem dom is ready...
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
var counter = 0;
function AddFileUpload()
{
var div = document.createElement('DIV');
div.innerHTML = '<input id="file' + counter + '" name = "file' + counter + '" type="file" /><input id="Button' + counter + '" type="button" value="Remove" onclick = "RemoveFileUpload(this)" />';
document.getElementById("FileUploadContainer").appendChild(div);
counter++;
}
function RemoveFileUpload(obj)
{
return false;
}
(文档).ready( function (){ AddFileUpload(); }); < / 脚本 > < /head > < 正文 > < div =" FileUploadContainer" < > < 输入 =" 按钮" 值 添加" onclick =" AddFileUpload();返回false;" < /body > < /html > < /html >
(document).ready(function () { AddFileUpload(); }); </script> </head> <body> <div id="FileUploadContainer"></div> <input type="button" value="Add" onclick="AddFileUpload();return false;"> </body> </html></html>
只需使用onClick = javascriptmethod();老兄，它将调用javascript
just use onClick=javascriptmethod(); Dude it will call the javascript
