根据下拉选择启用和禁用以及清除文本区域框 [英] Enable and Disable and clear textarea box based on Dropdown selection

问题描述

大家好，

我正在尝试启用多行文本框，并根据待处理"的选择禁用并清除多行文本框.如果没有其他选择，我希望启用多行文本框.我正在尝试在SharePoint中使用JQuery来执行此操作 2013.到目前为止，我的代码在下面列出.但是，该警报根本无法收回任何价值.

I'm trying to Enable a multi-line textbox and disable and clear the multi-line text box based on the selection of Pending. If the selection is anything else, I want the multi-line text box to be enabled. I'm trying to do this using JQuery in SharePoint 2013. The code I have so far is listed below. However the alert isn't getting any value back at all.

$(document).ready(function(){

$(document).ready(function(){

var text = $(#id_of_Dropdown").val();

var text = $("#id_of_Dropdown").val();

警报(文本)；

if(text ==待处理")

if(text == "Pending")

{

     $("input [value $ ='Save Changes']").attr('disabled'，true);

      $("input[value$='Save Changes']").attr('disabled',true);

     $(" textarea [title $ = PM Comments']").attr('disabled'，true);

      $("textarea[title$=PM Comments']").attr('disabled',true);

}

else

      
{

$("input [value $ ='Save Changes']").attr('disabled'，false); $(" textarea [title $ = PM Comments']").attr('disabled'，false);

$("input[value$='Save Changes']").attr('disabled',false); $("textarea[title$=PM Comments']").attr('disabled',false);

}

})
