Change input with string of multiple checkbox values












0















I need to be able to set the onclick function without onclick being in the input tag. The below code works great, but the input tags are generated and I cannot add the onclick event to them. Jquery solution is fine too.






function setValue(){
var val="";
var frm = document.getElementById("form1");
var cbs = document.getElementById("form1")['amenities'];
for(var n=0;n<cbs.length;n++){
if(cbs[n].checked){
val+=cbs[n].value+",";
}
}
var temp = val.split(",");
temp.pop();
frm.textname.value=temp
}

    
<form id="form1">
<input type="checkbox" name="amenities" value="coffee" onclick="setValue(this.value);">
<input type="checkbox" name="amenities" value="tea" onclick="setValue(this.value);">
<input type="checkbox" name="amenities" value="beer" onclick="setValue(this.value);">
<input type="checkbox" name="amenities" value="soda" onclick="setValue(this.value);">
<input type="checkbox" name="amenities" value="orangejuice" onclick="setValue(this.value);">
<input type="text" name="textname">
</form>

Use the .map() function






$(".checkbox").change(function() {
$("#text").val( $('.checkbox:checked').map(function() { return this.value; }).get().join(','));
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="form1">
<input type="checkbox" class="checkbox" name="amenities" value="coffee" >
<input type="checkbox" class="checkbox" name="amenities" value="tea" >
<input type="checkbox" class="checkbox" name="amenities" value="beer" >
<input type="checkbox" class="checkbox" name="amenities" value="soda">
<input type="checkbox" class="checkbox" name="amenities" value="orangejuice" >
<input type="text" name="textname" id= "text">

    you can try this:



    $('input[type=checkbox]').change(function() {
    //logic goes here
    });

      Plain JS:



          var mForm = document.getElementById("form1");
      mForm.addEventListener("click", function(event){
      console.log("clicked", event.toElement); // do whatever you want with this element, add condition to sort checkboxes only
      });


      UPDATED:



      var frm = document.getElementById("form1");
      var cbs = document.getElementById("form1")['amenities'];

      function setValue(frm, cbs){
      var output = ;

      for( var n in cbs){
      if(cbs[n].checked){
      output.push(cbs[n].value);
      }
      }

      frm.textname.value=output.join();
      }

      frm.addEventListener("click", function(event){
      if (event.toElement.type == "checkbox") {
      setValue(frm, cbs);
      }
      });
