javascript to jsp [英] javascript to jsp
问题描述
...
<脚本类型> 如何在jsp中显示javascript'var'？ = 文本/ JavaScript的 >
... //我的代码来获取值。
var val = combo.getValue（）;
< / script>
< body>
值为：//在此处显示
< / body>
添加一个HTML元素，值将被显示并给它一个 id 。
<体>
值为：< span id =value>< / span>
< / body>
然后让JS通过 document.getElementById（）并修改其内部HTML。
document.getElementById（value）。innerHTML = val;
您只需确保在加载HTML页面后执行特定脚本。在 window.onload 期间或者在结束时放置或者将它包装在< script> < body> 函数中，您可以在某个事件上执行。
至于JSP部分，这里并不相关。所有的JSP都会生成并发送HTML / CSS / JS代码，从web服务器到webbrowser。 JavaScript对JSP一无所知，它可以看到并访问的是HTML / CSS，您可以通过右键单击webbrowser中的页面并选择查看源代码来查看HTML / CSS。

How to show a javascript 'var' in my jsp?
...
<script type="text/javascript">
... // My code to get the value.
var val = combo.getValue();
</script>
<body>
The value is : //to be displayed here
</body>
Add a HTML element which should mark the place where the value is to be displayed and give it an id.
<body>
The value is : <span id="value"></span>
</body>
Then let your JS access it by document.getElementById() and modify its inner HTML.
document.getElementById("value").innerHTML = val;
You only need to ensure that the particular script executes after the HTML page has loaded. Do it during window.onload or put the <script> at end of <body> or wrap it in a function which you execute on some event.
As to the JSP part, this is not relevant here. All JSP does is generating and sending HTML/CSS/JS code from webserver to webbrowser. JavaScript knows nothing about JSP, all it can see and access is HTML/CSS which you can also see by rightclicking the page in webbrowser and choosing View Source.
