提问by Mr.Chowdary
I want to set an HTML field's value using JavaScript when onclick
event is raised by clicking a button/hyperlink.. I Googled and found many articles using the name
attribute, but I want to set the value using the field's id
only.
我想在onclick
通过单击按钮/超链接引发事件时使用 JavaScript 设置 HTML 字段的值。我在 Google 上搜索并找到了许多使用该name
属性的文章,但我想id
仅使用该字段来设置值。
