问题描述
这是我的代码
< html >
< 表格 名称 = form1 方法 = 发布 action = < span class =code-keyword>>
< label = 乌尔ls > < / label >
< 输入 类型 = 提交 名称 = 返回 id = 返回 value = < önClick = myIframe.history.back（） >
< 输入 < span class =code-attribute> type = submit 名称 = 转发 id = forward value = > onClick = myIframe.history.forward（） >
< input type = 提交 name = 搜索 id = 搜索 value = Go onClick = LoadPage（） >
< 输入 type = text 名称 = urls id = 网址 value = http： // >
< / form >
< < span class =code-leadattribute> iframe src = http://www.google.com width = 500 height = 400 frameborder = 0 id = myIframe > < / iframe >
< script language = javascript < span class =code-keyword>>
function LoadPage（）{
var objFrame = document .getElementById（ myIframe）;
objFrame.src = document .getElementById（ URL）值。
}
< / 脚本 >
< / html >
我似乎无法找到这个代码的问题，它在Dreamweaver中工作，但一旦它保存，我文档点击它，在我的chrome broswer运行它，它不工作？有人可以解释一下吗？
解决方案
你错过了< head>和< body>大多数浏览器认为这些部分对于格式良好的HTML文档至关重要。您还应该将您的Javascript代码放在< head>中部分，除非你有特别的理由将它放在页面上。
< html>
< head>
< title>我的网页< / title >
< script language = 的JavaScript>
function LoadPage（）{
var objFrame = document .getElementById（ myIframe）;
objFrame.src = document .getElementById（ URL）值。
}
< / script>
< / head >
< body>
< form name = form1 method = post action = >
< label for = urls > < / label >
< input type = submit name = back id = back value = < onClick = myIframe.history.back（）>
< input type = submit name = forward id = forward value = > onClick = myIframe.history.forward（）>
< input type = submit name = 搜索 id = 搜索 value = Go onClick = LoadPage（）>
< input type = text name = urls id = 网址 value = http：//>
< / 表格 >
< iframe src = http://www.google.com width = 500 height = 400 frameborder = 0 id = myIframe> < / iframe >
< / body >
< / html >
this is my code
<html>
<form name="form1" method="post" action="">
<label for="urls"></label>
<input type="submit" name="back" id="back" value="<" önClick="myIframe.history.back()">
<input type="submit" name="forward" id="forward" value=">" onClick="myIframe.history.forward()">
<input type="submit" name="Search" id="Search" value="Go" onClick="LoadPage()">
<input type="text" name="urls" id="URL" value="http://">
</form>
<iframe src="http://www.google.com" width="500" height="400 frameborder="0" id="myIframe"></iframe>
<script language="javascript">
function LoadPage(){
var objFrame=document.getElementById("myIframe");
objFrame.src=document.getElementById("URL").value;
}
</script>
</html>
I can't seem to find the problem with this code, it works in dreamweaver, but once Its saved and I docuble click on it, to run it in my chrome broswer, it dosen't work??? can some one please explain?
解决方案
Well you are missing both the <head> and <body> sections, which most browsers regard as essential for a 'well-formed' HTML document. You should also put your Javascript code in the <head> section, unless you have a specific reason for putting it further down on the page.
<html> <head> <title>My Page</title> <script language="javascript"> function LoadPage() { var objFrame = document.getElementById("myIframe"); objFrame.src = document.getElementById("URL").value; } </script> </head> <body> <form name="form1" method="post" action=""> <label for="urls"></label> <input type="submit" name="back" id="back" value="<" onClick="myIframe.history.back()"> <input type="submit" name="forward" id="forward" value=">" onClick="myIframe.history.forward()"> <input type="submit" name="Search" id="Search" value="Go" onClick="LoadPage()"> <input type="text" name="urls" id="URL" value="http://"> </form> <iframe src="http://www.google.com" width="500" height="400" frameborder="0" id="myIframe"></iframe> </body> </html>
