如何完全更改div onclick的内容？

Question

I'm only starting to delve into javascript and have no real knowledge of how to work with jQuery, but I'm working on a page which features a control panel. I'm trying to get the functions of the control panel to change on clicking a button on it.

Here's what I have so far;

html:

<div id="functions">
  <button id="prob" onclick="myproblem()" type="button" title="prob"></button>
  <button id="button1" onclick="works1()" type="button" title="button1"></button>
  <button id="button2" onclick="works2" type="button" title="button2"></button>
</div>

Javascript:

function myproblem() {
document.getElementById("functions").html('
  <button id="prob" onclick="myproblem()" type="button" title="prob"></button>
  <button id="button3" onclick="works3()" type="button" title="button3"></button>
  <button id="button4" onclick="works4()" type="button" title="button4"></button>');
}

The button I want to use to change the html is contained within the div which is getting changed. There are other onclick functions in that div which were working fine until I wrote the myproblem() code into my js file. With that section of code there, none of my js works.

This is a localhosted page, it won't be online.

I'm assuming I need to use jQuery to pull this off, but I have no idea how.

Thanks,

Answer 1

Use the innerHTML() method in JavaScript:

function myproblem() {
    document.getElementById("functions").innerHTML ='<button id="prob" onclick="myproblem()" type="button" title="prob"></button> <button id="button3" onclick="works3()" type="button" title="button3"></button> <button id="button4" onclick="works4()" type="button" title="button4"></button>'
}

In Jquery you can use the html method

$(".functions").html('Your html code goes here')

<div class="temp01" style="display:none">
   <button id="prob" onclick="myproblem('temp02')" type="button" title="prob"></button>
   <button id="button1" onclick="works1()" type="button" title="button1"></button>
   <button id="button2" onclick="works2" type="button" title="button2"></button>
</div>
<div class="temp02" style="display:none">
   <button id="prob" onclick="myproblem('temp01')" type="button" title="prob"></button>
   <button id="button3" onclick="works3()" type="button" title="button3"></button>
   <button id="button4" onclick="works4()" type="button" title="button4"></button>
</div>
<div class="functions">
   <button id="prob" onclick="myproblem('temp02')" type="button" title="prob"></button>
   <button id="button1" onclick="works1()" type="button" title="button1"></button>
   <button id="button2" onclick="works2" type="button" title="button2"></button>
</div>

<script>
   function myproblem(x){   //x could be "temp01" or "temp02"
        $(".functions").html("");
        $("." + x).clone().attr("id","functions").show().appendTo(".functions");
   }
</script>
