单击按钮时设置表单变量 [英] Set a form variable when button is clicked

问题描述

谁能帮我用JavaScript编写代码.我是新手.

我有保存按钮.单击保存"按钮后，我目前将其配置为<输入类型=按钮VALUE =保存" ONCLICK ="savemethod()">

我需要编写代码，以便在单击保存按钮时，需要在savemethod()中设置表单变量，以便以后可以在代码中使用该变量.

将变量设置为某种值(整数或true)后，我将编写如下内容:
如果saveformvariable = true/1
然后写入数据库(我的意思是更新数据库)，否则不要更新.

单击按钮时如何设置表单变量.有人可以帮我吗?

这有点紧急
提前非常感谢.

Can anyone help me to write the code in JavaScript. I am new to it.

I have the save button. When Save button is clicked which I presently configured like "<INPUT TYPE=button VALUE="Save" ONCLICK="savemethod()">

I need to write the code so that when the save button is clicked, I need to set the form variable in savemethod() so that I can use that variable later in the code.

After it sets the variable to something(either integer or true), I will write something like this:
If saveformvariable = true/1
then write to database (i mean update to database) else Don''t update.

How can I set the form variable when the button is clicked. Can someone help me out please?

It is a bit urgent
Thanks a lot in advance.
