想清除文本框+焦点文本框+阻止asp.net回发同一个按钮

Question

我在ASP.NET上有这个简单的html按钮，按下按钮我想清除textbox1，专注于textbox1并防止回发。我怎样才能做到这一点？防止回发也会停止按钮清除和聚焦的能力。感谢。

$("#button1").click(function () {
     var text1 = $("#textbox1").val();
     $.connection.moveshapehub.server.sendmessage1(text1); //send text to hub
     //want to clear textbox1 + focus on textbox1
     return false; //prevent asp.net postback
});

Answer 1

$("#button1").click(function (e) {
      e.preventDefault();
      var text1 = $("#textbox1").val();
      $.connection.moveshapehub.server.sendmessage1(text1); //send text to hub
      //want to clear textbox1 + focus on textbox1
      $("#textbox1").focus().val("");
      return false; //prevent asp.net postback
 });
