提问by Prady
I am trying to get a value fro query string and assign that value into a textbox. I am able to get the value from query string but unable to assign it to textbox.
我正在尝试从查询字符串中获取一个值并将该值分配给一个文本框。我能够从查询字符串中获取值，但无法将其分配给文本框。
document.getElementByName('Contact0Email').Value = email;
Tried the above code but doesn't seem to be working. Though the alert of email gives the right value.
尝试了上面的代码，但似乎不起作用。尽管电子邮件的警报提供了正确的价值。

You need a lower-case valueand a plural Elements:
你需要一个小写value和一个复数Elements：
document.getElementsByName('Contact0Email')[0].value = email;
You need the [0]to get the first element in the list. Names don't have to be unique like ids.
您需要[0]获取列表中的第一个元素。名称不必像 id 一样唯一。
