Question

可以在将值添加到输入文本框后对“输入”进行编程吗？

如果是，我需要以下代码的帮助。它不会触发“ENTER”按键。

我的代码如下：

$('#clo_cart').click( function () {

/*Save ENTER in variable*/
var eneterKey = jQuery.Event("keydown");
eneterKey.which = 13; 
eneterKey.keycode = 13;

$("#scan_char").focus().val('CLOSECTN').trigger(eneterKey);
}//end of button click

请帮助

Answer 1

只需将handlers: # Serve images and JSON as static resources. - url: /(.+\.(gif|png|jpg|json|ico))$ static_files: \1 upload: .+\.(gif|png|jpg|json|ico)$ application_readable: true - url: \/(static)\/(index)\.html static_files: static/\1/index.html upload: static\/index.html - url: / script: roomusage.app login: required secure: always - url: /welcome script: roomusage.app login: required secure: always - url: /record script: record_usage.app login: required secure: always事件替换为appcfg.py: error: Error parsing C:\gcloud\dev-myapp\app.yaml: Unable to assign value '\/(static)\/(index)\.html' to attribute 'url': Value '\/(static)\/(index)\.html' for url does not match expression '^(?:(?!\^)/.*|\..*|(\(.).*(?!\$).)$' in "C:\gcloud\dev-myapp\app.yaml", line 25, column 8. 2017-12-08 09:27:50 (Process exited with code 2)事件即可。他们使用keydown属性的方式有所不同。这可能是其中两个使用keypress的不同值的情况之一。

event.which

另请注意，event.which属性已被弃用。您可以与var eneterKey = jQuery.Event("keypress");属性进行比较。当要模拟回车键时，它应该具有值which。

event.key

Answer 2

以下代码对我来说很好。

  $('#clo_cart').click( function () {

     $("#scan_char").focus().val('CLOSECTN').trigger(enterKey());

  }//end of button click

    /* Function to allow program keypress ENTER */
    function enterKey() {

       return $.Event( "keypress", { which: 13 } );

    }

Answer 3

您可以使用此代码

$('#clo_cart').click( function () {

var e = $.Event( "keypress", { which: 13 } );
$("#scan_char").focus().val('CLOSECTN').trigger(e);

}//end of bu

以编程方式触发“ENTER”
