Executing Javascript code "on the spot" in Chrome?
提问by Gadi A
I have a page in chrome which contains many textboxes and I wish to feed values automatically to them. I already have the list of name-value pairs, so if I could simple execute a series of Javascript commands on the form "document.getElementsByName(NAME)[0].value = VALUE;" I'll be done (I hope...)
我有一个 chrome 页面，其中包含许多文本框，我希望自动向它们提供值。我已经有了名称-值对列表，所以如果我可以简单地在表单“document.getElementsByName(NAME)[0].value = VALUE;”上执行一系列 Javascript 命令 我会完成（我希望...）
So the question is - can I run a JS code "on the spot", or do I have to use a content script somehow?
所以问题是 - 我可以“当场”运行 JS 代码，还是必须以某种方式使用内容脚本？

Right click on the page and choose 'inspect element'. In the screen that opens now (the developer tools), clicking the second icon from the left @ the bottom of it opens a console, where you can type javascript. The console is linked to the current page.
右键单击页面并选择“检查元素”。在现在打开的屏幕（开发人员工具）中，单击左侧@底部的第二个图标会打开一个控制台，您可以在其中键入 javascript。控制台链接到当前页面。

I'm not sure how far it will get you, but you can execute JavaScript one line at a time from the Developer Tool Console.
我不确定它会让您走多远，但您可以从Developer Tool Console一次执行一行 JavaScript 。

Have you tried something like this? Put it in the head for it to work properly.
你有没有尝试过这样的事情？把它放在头上，让它正常工作。
<script type="text/javascript">
document.addEventListener("DOMContentLoaded", function(){
//using DOMContentLoaded is good as it relies on the DOM being ready for
//manipulation, rather than the windows being fully loaded. Just like
//how jQuery's $(document).ready() does it.
//loop through your inputs and set their values here
}, false);
</script>
