javascript button click using curl
提问by qmaruf
I have parsed a page using curl and it contains some check box and a 'select all' and a 'submit' button . Clicking the button selects every check box.'select all' button triggers a javascript function which actually select all check box.
我使用 curl 解析了一个页面，它包含一些复选框和一个“全选”和一个“提交”按钮。单击该按钮会选择每个复选框。“全选”按钮会触发一个 javascript 函数，该函数实际上选择所有复选框。
Now i need to click 'select all' and 'submit' button.How can I do this ??
现在我需要点击“全选”和“提交”按钮。我该怎么做？？
Here is the button code:
这是按钮代码：
input type="button" onclick="SelectAll(137)" value="Select All"
Here is the js function:
这是js函数：
function SelectAll(n)
{
for(i=0;i<n;i++)
document.getElementById("ch"+i).checked=true;
}

You can't. If you must use cURL, you'd have to manually craft the POST request yourself. This would involve finding the names of all the checkboxes and sending a bunch of checkbox1=on&checkbox2=on&...in the POST body. See http://davidwalsh.name/execute-http-post-php-curlfor a general example of a POST request through cURL with PHP.
你不能。如果必须使用 cURL，则必须自己手动制作 POST 请求。这将涉及查找所有复选框的名称并checkbox1=on&checkbox2=on&...在 POST 正文中发送一堆。请参阅http://davidwalsh.name/execute-http-post-php-curl以了解通过 cURL 使用 PHP 进行 POST 请求的一般示例。
Another option would be to use something like Selenium Web Driver, which pretty much allows you to script a web browser like Firefox that can run JavaScript, click things, etc.
另一种选择是使用Selenium Web Driver 之类的东西，它几乎允许您编写可以运行 JavaScript、单击内容等的 Firefox 等 Web 浏览器的脚本。

Pass a parameter in with your Curl request that gets parsed by jQuery on its $(document).ready(). There's some plugins that help with parsing parameters.
将参数与您的 Curl 请求一起传递，该参数由 jQuery 在其 $(document).ready() 上解析。有一些插件可以帮助解析参数。
Something like
就像是
$(document).ready(function(){
var buttonPress = $.param("buttonPress");
if (buttonPress == true)
$("#myButton").click();
});
