javascript - casperjs (phantomjs) 网站更新后无法提交表单

Question

直到最近网站更新后，我的脚本才运行了一段时间。

https://www.vicroads.vic.gov.au/registration/buy-sell-or-transfer-a-vehicle/buy-a-vehicle/check-vehicle-registration/vehicle-registration-enquiry

我所做的就是填写表格，单击“提交”并抓取结果。

现在看来，无论我做什么，单击，发送回车键......等等，表单都不会提交。

我有来自 casper 的以下调试行:

我也尝试过等待包含结果的选择器，但它从未到达。

任何 phantomjs/casperjs 大师都有什么妙招吗？

您点击的不是提交按钮，而是整个表单。

this.click('form#form1');

处方集不是按钮，因此不是“可点击的”。您应该寻找提交按钮并单击它。在这种情况下，我这样做是正确的:

this.click('"#main input[type='submit']"');

就是这样。

使用'form#form1'，您实际上是在寻找submit，但我不认为直接调用submit表单将触发附加到按钮的 onClick 事件，因此如果您想 100% 模拟用户操作，最好单击按钮而不是直接提交表单。

要直接提交表单，只需删除 fill 方法末尾的 false 属性即可。
