Move mouse pointer in JavaScript
提问by Brian
Is it possible to move the mouse so that it is positioned inside a text input using JavaScript?
是否可以移动鼠标使其位于使用 JavaScript 的文本输入内？
回答by jasonbar
I don't know about moving the actual rendered mouse, but could you just set the focus to the element?
我不知道移动实际渲染的鼠标，但你能把焦点设置在元素上吗？
document.getElementById('the_text_input_id').focus()

Please see this question:
请看这个问题：
Besides that, I think you are committing major design mistake by taking control of any of the users input in any way (maybe besides setting the focus of a form element)
除此之外，我认为您通过以任何方式控制任何用户输入（也许除了设置表单元素的焦点）而犯了重大的设计错误

Here is a function that select text in an input or textarea:
这是一个在输入或文本区域中选择文本的函数：
function textSelect(inp, s, e) {
e = e || s;
if (inp.createTextRange) {
var r = inp.createTextRange();
r.collapse(true);
r.moveEnd('character', e);
r.moveStart('character', s);
r.select();
}else if(inp.setSelectionRange) {
inp.focus();
inp.setSelectionRange(s, e);
}
}
To place the cursor at the 12th position:
将光标置于第 12 个位置：
textSelect(document.getElementById('theInput'), 12);
To select a portion of the input field:
要选择输入字段的一部分：
textSelect(document.getElementById('theInput'), 12, 15);

It would be a huge [security?] issue if they allowed for something like this.
Imagine: you have a setInterval(function(){moveMouseToTopLeftCorner and alert garbage}, 1)...
The user would have his mouse moved to the top left. And then alert would show up [which could be closed with enter].. upon which an alert would immediately pop up again.
如果他们允许这样的事情，那将是一个巨大的 [安全？] 问题。想象一下：你有一个 setInterval(function(){moveMouseToTopLeftCorner and alert Garbage}, 1) ...
用户会将他的鼠标移到左上角。然后警报会出现[可以用回车关闭]..然后会立即再次弹出警报。
You'd actually have to use your keyboard to open taskmanager and kill the browser >_>
您实际上必须使用键盘打开任务管理器并关闭浏览器 >>>
However, it is probably possible with ActiveX [although thats IE only... and dumb]
但是，使用 ActiveX 可能是可能的 [虽然那只是 IE ......而且愚蠢]
