触发复选框单击按钮

Question

I'm trying to change my 'send' button which onClick sends a message from an input box to a div, to also trigger the click of a 'checkbox' input.

HTML

<button type="submit" class="btn btn-default">Post</button> 
   <input name="stry" type="text" id="stry"/> 
   <input name="nope" type="text" id="message-input"/>
        <input type="checkbox" name="sendsms" onclick="copyStory(this)">

*These buttons are actually in a form

JS

 function copyStory(ch) {
     if (ch.checked)
         var text1 = document.getElementById("message-input").value;
     else
         text1 = '';
     document.getElementById("stry").value = text1;
 }

I've searched around but I can't find a way to make the send button trigger the checkbox, any suggestions?

Answer 1

So what you need is to have same handler for both onclick and onchange events. Try this way,

HTML :

<input type="button" id="sendButton" value="Send" onclick="copyStory(this)" />
<input name="nope" type="text" id="message-input"/>
<input type="checkbox" name="sendsms" onchange="copyStory(this)"/>

<div id="msgDiv"></div>

javaScript :

 function copyStory(ch) {
     var text1
     if (ch.checked || ch.id == "sendButton")
         text1 = document.getElementById("message-input").value;
     else
         text1 = document.getElementById("msgDiv").innerText = "";

     document.getElementById("msgDiv").innerText = text1;
 }
