javascript - How do I disable text areas based on what radio button is checked when the page loads? -


i want improve upon script disabling text areas radio button selection. when "yes" selected text areas should disabled , enabled when "no" selected.

what need change text areas disabled when page first loads , if correct radio button checked?(yes checked default if no change has been made)

please bare in mind page refreshed , redirected need check actual selection on radio buttons. setting them disabled on load before disabled text areas when had correct radio button selected.

html

<div class="group">     <input type="radio" name="choice1" value="yes" checked/>yes     <input type="radio" name="choice1" value="no" />no </div> <div class="group">     <input type="radio" name="choice2" value="yes" checked/>yes     <input type="radio" name="choice2" value="no" />no </div> <div class="group">     <input type="radio" name="choice3" value="yes" checked/>yes     <input type="radio" name="choice3" value="no" />no </div>         <div>     <textarea data-trigger="choice1" rows="4" cols="20"></textarea>     <textarea data-trigger="choice2" rows="4" cols="20"></textarea>     <textarea data-trigger="choice3" rows="4" cols="20"></textarea> </div>

javascript/jquery

    $(function () {      var $choices = $(".group").find(":radio");     $choices.on("change", function () {         var $this = $(this);         var choicename = $this.attr('name');          var tarea = $('[data-trigger="' + choicename + '"]');         if ($this.val() === "yes") {             tarea.val('');             tarea.prop('readonly', true);             tarea.css('background-color', '#ebebe4');         } else {             tarea.prop('readonly', false);             tarea.css('background-color', '#ffffff');         }     }); });

hope that's clear enough.

try

$(".group").find(":radio[value=yes]:checked").each(function () {     $('[data-trigger="' + $(this).attr("name") + '"]').prop('readonly', true).css('background-color', '#ebebe4'); });
