尝试用greasemonkey模拟点击按钮

发布于 2024-10-22 18:51:02 字数 439 浏览 3 评论 0原文

我正在尝试编写一个greasemonkey 脚本，通过浏览器更新一组项目的库存。为此，我需要自动填写一些表单并模拟鼠标单击提交按钮。我的表格填写得很好，但我被困在按钮提交上。

这是我试图模拟点击的按钮的 HTML

<input type="submit" value="Find" style="" name="process-form" onclick="imhocaller.value='find-resources-page.left'; imhoaction.value='process-form';">

我尝试做类似的事情，但没有任何运气。

document.getElementsByName('process-form').submit();

如果需要，我可以发布更多代码。谢谢你！

I'm trying to write a greasemonkey script that updates inventory for a collection of items through the browser. To do this I need to autofill a few forms and simulate a mouseclick on the submission button. I have the forms filling out fine, but I'm stuck on the button submission.

Here is the HTML for the button I am trying to simulate clicking

<input type="submit" value="Find" style="" name="process-form" onclick="imhocaller.value='find-resources-page.left'; imhoaction.value='process-form';">

I tried doing something like this, but haven't had any luck.

document.getElementsByName('process-form').submit();

I can post more code if needed. Thank you!

想通了。需要使用 .click() 而不是 .submit()。
我还需要按照 Georgy 的建议添加 [0]。

document.getElementsByName('process-form')[0].click();

Figured it out. needed to use .click() instead of .submit().
I also needed to add the [0] as Georgy suggested.

document.getElementsByName('process-form')[0].click();

您还可以通过最新的浏览器分派自定义点击事件，并在 IE 中“触发”onclick 事件。这是最近的一项功能，允许对事件进行大量控制。

var button = document.getElementById("test");
button.onclick = function()
{
    alert("event was dispatched on me");      
}
if(document.createEvent)
{
    var click = document.createEvent("MouseEvents");
    click.initMouseEvent("click", true, true, window,
    0, 0, 0, 0, 0, false, false, false, false, 0, null);
    button = document.getElementById("test");
    button.dispatchEvent(click);
    button.focus();
}else if(document.documentElement.fireEvent)
{
    button = document.getElementById("test");
    button.fireEvent("onclick");
    button.focus();
}

请注意，您需要监听该事件在发送之前。

You can also dispatch a custom click event via most recent browsers and "fire" an onclick event in IE. This is a recent feature that allows tons of control over events.

var button = document.getElementById("test");
button.onclick = function()
{
    alert("event was dispatched on me");      
}
if(document.createEvent)
{
    var click = document.createEvent("MouseEvents");
    click.initMouseEvent("click", true, true, window,
    0, 0, 0, 0, 0, false, false, false, false, 0, null);
    button = document.getElementById("test");
    button.dispatchEvent(click);
    button.focus();
}else if(document.documentElement.fireEvent)
{
    button = document.getElementById("test");
    button.fireEvent("onclick");
    button.focus();
}

Do note that you need to listen for the event before dispatching it.
