用js函数显示HTML表单的结果
[英]displaying result of HTML form on with js function
问题描述
I know that you cannot really have variables in html, but I'm wondering if this is possible. 
我知道您实际上不能在html中有变量，但是我想知道是否可行。 I have searched around and cannot find anything that clearly answers my question. 我四处搜寻，找不到任何能清楚回答我问题的内容。 Hopefully someone hear can point me in the right direction. 希望有人听到可以指出我正确的方向。 Here's what I have in mind: 这就是我的想法：
<!DOCTYPE html>
<html>
<body>
<input type="text" name="test">
<input type="submit" onclick="myFunction(test)">
<script type="text/javascript">
function myFunction(test)
{
alert("Welcome " + test);
}
</script>
</body>
</html>
Would this work or something like it? 这项工作或类似的工作吗？ Thanks, Sam 谢谢山姆

If you mean using the contents of an input as a variable: 如果要使用输入内容作为变量：
<!DOCTYPE html>
<html>
<body>
<input type="text" id="some_id" name="test">
<input type="submit" onclick="myFunction(document.getElementById('some_id').value)">
<script type="text/javascript">
function myFunction(test)
{
alert("Welcome " + test);
}
</script>
</body>
</html>

What I understood from your question is you want to access <input> and send it to function(test) try this: 我从您的问题中了解到，您想访问<input>并将其发送给function(test)尝试以下操作：
<input type="text" name="test" id="test"> <-- Give ID here
<input type="submit" onclick="myFunction(test)"> <--Send same ID here
<script type="text/javascript">
function myFunction(test)
{
alert("Welcome " + test.value);
}
</script>
</body>
