在JQuery中键入将INPUT附加到TEXTAREA [英] Append INPUT to TEXTAREA as being typed in JQuery

问题描述

我有一个INPUT文本框.

I have an INPUT text box.

当有人在输入"文本框中键入内容时，我需要它在TEXTAREA值的后面添加/添加.

As someone types into the INPUT text box, i need it to append/add-to a TEXTAREA value.

假设用户在文本框中输入"12345".

Lets say user types '12345' into the text box.

textarea(默认值="Comment:")将自动添加:'Comment:12345'.在键入时添加"12345".

The textarea (default value="Comment: ") will automatically add: 'Comment: 12345'. Adding '12345' as they type.

推荐答案

假设area是您的文本区域的ID，text是您的文本框的ID，

Assuming area is the id of your textarea and text the id of your textbox,

$(function() {

  var areaText = $('#area').val();  

  $('#text').bind('keyup keypress', function() { 
      $('#area')[0].value = areaText + $(this)[0].value;
  });

});
