使用Java脚本功能重新加载HTML元素？
[英]Reload an HTML element using a java script function?
问题描述
Well, I am sort of asking a 2 part question but answering either part would help me out. 
好吧，我有点想问一个分为两部分的问题，但是回答任何一部分都可以帮助我。 I will be direct in my question and skip straight to what I need help with. 我将直接回答我的问题，直接跳过我需要的帮助。 I am trying to use a Javascript function to define certain elements of an iframe so the user can decide the source, height, and width. 我正在尝试使用Javascript函数来定义iframe的某些元素，以便用户可以确定源，高度和宽度。 The code I have right now is as shown below. 我现在拥有的代码如下所示。
<script language="javascript"> window.onload = webPage; function webPage(){ var page = prompt("please enter the website","www.google.com"); var height = prompt("Please enter the height of the frame","800"); var width = prompt("Please enter the width of the frame","600"); } </script>
<iframe src=page height=height width=width> </iframe>
Is there a way i can reload the iFrame and have it use the user inputs as the elements with my current code? 有没有一种方法可以重新加载iFrame并将其使用用户输入作为当前代码的元素？ Is there something else that i need to do to have the variables be used for the iFrame? 为了将变量用于iFrame，我还需要做其他事情吗？ Thanks for anyone who looks at my question and looking forward to your answer. 感谢您关注我的问题并期待您的回答。

First initialize the IFrame with blank values and with one unique ID and then append user input. 首先使用空白值和一个唯一ID初始化IFrame，然后追加用户输入。
Here is the working JSFiddle Link 这是工作中的JSFiddle Link
Dynamically Changing Values: 动态更改值：
<!DOCTYPE html>
<html>
<head>
<title>Demo</title>
</head>
<body>
<iframe id="icereaper666" src="" height="0" width="0"></iframe>
<script language="javascript">
window.onload = webPage;
function webPage(){
var page = prompt("please enter the website","http://www.w3schools.com/");
var height = prompt("Please enter the height of the frame","400");
var width = prompt("Please enter the width of the frame","400");
var iframeElement = document.getElementById("icereaper666");
iframeElement.src = page;
iframeElement.height = height;
iframeElement.width = width;
}
</script>
</body>
</html>
Note: You can also create IFrame element dynamically using createElement . 注意：您也可以使用createElement动态创建IFrame元素。 Check this out
Using Create Element: 使用创建元素：
<!DOCTYPE html>
<html>
<head>
<title>Demo</title>
</head>
<body>
<script language="javascript">
window.onload = webPage;
function webPage(){
var page = prompt("please enter the website","http://www.w3schools.com/");
var height = prompt("Please enter the height of the frame","400");
var width = prompt("Please enter the width of the frame","400");
var iframeElement = document.createElement("iframe");
iframeElement.src = page;
iframeElement.height = height;
iframeElement.width = width;
document.body.appendChild(iframeElement);
}
</script>
</body>
</html>
