[英]How to programmatically click on text input in WebBrowser using C#
I have opened a website using WebBrowser. 我已经使用WebBrowser打开了一个网站。 Now I would like to programmatically click input text (textbox) field.
现在,我想以编程方式单击输入文本(文本框)字段。 I can not use focus because this website uses JS to unlock this field only if it's clicked and I've tried also this:
我无法使用焦点,因为此网站仅在单击该字段时使用JS来解锁该字段,并且我也尝试过以下操作:
Object obj = ele.DomElement;
System.Reflection.MethodInfo mi = obj.GetType().GetMethod("click");
mi.Invoke(obj, new object[0]);
But it returns mi = null. 但它返回mi = null。 How to do this so it will work?
如何做到这一点将起作用?
Very similar to my answer on your other question . 与我关于另一个问题的回答非常相似。
Get an HtmlElement respresentative of your textbox, and call HtmlElement.InvokeMember("click") on it. 获取代表您的文本框的HtmlElement,然后在其上调用HtmlElement.InvokeMember(“ click”)。
If you can, use: 如果可以,请使用:
webbrowser1.Navigate("javascript:document.forms[0].submit()")
or something similar. 或类似的东西。 For me, it's been much easier and more accurate.
对我来说,它变得更加容易和准确。
To fill-up a text field on a webpage: 要填写网页上的文本字段,请执行以下操作:
string code ="";
code = code + "var MyVar=document.getElementById('tbxFieldNameOnWebPage');if(MyVar != null) MyVar.value = 'SOMEVALUE';";
domDocument.parentWindow.execScript(code, "JScript");
Then To Click a button on a webpage:
code = "";
code = "var SignupFree = document.getElementsByTagName('button')[1];";
code = (code + " SignupFree.click();");
domDocument.parentWindow.execScript(code, "JScript");
you can also use document.getElementById('buttonID');
您还可以使用
document.getElementById('buttonID');
instead of document.getElementsByTagName('button')[1];
而不是
document.getElementsByTagName('button')[1];
but an id must be provided for this button on that particular webpage. 但必须在该特定网页上为此按钮提供一个ID。
在HtmlElement或Browser.InvokeScript函数上使用InvokeMethhod。
