Set Input Value to Javascript Variable
提问by JakeTheSnake
Let's say I have a variable called x in javascript. How can I set the value of a text input (HTML) to that variable? For example:
假设我在 javascript 中有一个名为 x 的变量。如何将文本输入 (HTML) 的值设置为该变量?例如:
The value of the input will now be Swag
输入的值现在将是 Swag
<input type="text" value="Swag" />
But if I want the value to be a javascript variable? How do I do? Something like this? (I am just guessing, trying to make my point clear)
但是,如果我希望该值是一个 javascript 变量呢?我该怎么办?像这样的东西?(我只是猜测,试图阐明我的观点)
<input type="text" value="variable.x" />
