Change check value checkbox form ( Awesomium VB.net)

我都试过了,但都不行。谁能帮帮我?

WebControl1.ExecuteJavascript("document.getElementById('#signupForm_confirm_terms').prop('checked'", "true")

WebControl1.ExecuteJavascript("document.getElementById('#signupForm_confirm_terms').attr('checked'", "true")

提前致谢:)

尝试:
