自动点击 JavaScript 按钮

发布于 2024-10-31 15:13:56 字数 1118 浏览 0 评论 0原文

所以我有一个带有如下代码的按钮：

<div style="text-indent: 0pt; visibility: inherit;" id="button5061">
    <a title="Continue" href="javascript:if(%20button5061.hasOnUp%20)%20button5061.onUp()" name="button5061anc">
        <img width="82" height="25" border="0" style="cursor: pointer;" alt="Continue" src="images/continueoff.gif" name="button5061Img">
    </a>
</div>

我需要用 javascript 单击它。现在我正在使用 firefox 扩展 Chickenfoot，它允许我使用 javascript 解释器和一些自定义命令来编写网站脚本。

我尝试使用 xPath (//div/a[@title='Continue']/..) 选择它，它找到了它，但是当我单击() 时，什么也没有发生。以下是我尝试过的一些事情：

click(find(new XPath("//img[@alt='Continue']/..")))
click(find(new XPath("//img[@alt='Continue']/../..")))
click("continue")
click("Continue")
click("images/continueoff.gif")
click("continueoff.gif")
click(find("Continue"))
click(find("Continue").element)
click(find("images/continueoff.gif"))

我知道这是一个相当具体的问题，但任何关于尝试什么的想法将不胜感激。

So I have a button with code like this:

<div style="text-indent: 0pt; visibility: inherit;" id="button5061">
    <a title="Continue" href="javascript:if(%20button5061.hasOnUp%20)%20button5061.onUp()" name="button5061anc">
        <img width="82" height="25" border="0" style="cursor: pointer;" alt="Continue" src="images/continueoff.gif" name="button5061Img">
    </a>
</div>

And I need to click it with javascript. Right now I am using the firefox extension Chickenfoot which allows me to script the site with a javascript interpreter with some custom commands.

http://groups.csail.mit.edu/uid/chickenfoot/api.html

I have tried selecting it with xPath (//div/a[@title='Continue']/..) which finds it, but when I click() it nothing happens.
Here are some of the things I have tried:

click(find(new XPath("//img[@alt='Continue']/..")))
click(find(new XPath("//img[@alt='Continue']/../..")))
click("continue")
click("Continue")
click("images/continueoff.gif")
click("continueoff.gif")
click(find("Continue"))
click(find("Continue").element)
click(find("images/continueoff.gif"))

I know this is a rather specific quesiton but any ideas on what to try would be much appreciated.

如果您尝试模拟用户点击它：

您可以像这样模拟点击：document.getElementById('theSubmitButton').click();

这是给您的一个示例：http://jsfiddle.net/gasWZ/1/

如果这不是您想要做的，您可以吗多解释一下吗？

将锚对象传递给函数并评估 name 属性不是很有效吗？

将 href 属性设置为 #
调用函数并传递 obj

<div style="text-indent: 0pt; visibility: inherit;" id="button____"> <a title="Continue" href="#" name="button____anc"> <img width="82" height="25" border="0" style="cursor: pointer;" alt="Continue" src="images/continueoff.gif" name="button____Img"> </a> </div>

Wouldn't it be effective to pass the anchor object to your function and evaluate the name attribute?

set the href attribute to #
call the function and pass the obj

<div style="text-indent: 0pt; visibility: inherit;" id="button____"> <a title="Continue" href="#" name="button____anc"> <img width="82" height="25" border="0" style="cursor: pointer;" alt="Continue" src="images/continueoff.gif" name="button____Img"> </a> </div>
