Checkbox value not being fetched in Firefox but works in chrome












-1















Am working on a drop-down menu whereby I want to fetch the value of the option the user selected on the drop-down list. It works well on Chrome using onmousedown event but does not work on Firefox,, The value gets alerted in Chrome but not on Firefox.
Please assist?

<div class="check-now" style="width: 100%;">
<h1 class="cover-travel">Child(ren)</h1>
<select name="child" id="child" onmousedown="this.value='';" onchange="checkChild(this.value)">
<option value="0">None</option>
<option value="1">1</option>
<option value="2"> 2</option>
<option value="3"> 3 </option>
<option value="4"> 4 </option>
<option value="5"> 5 </option>
</select>
</div>


Function being called which works well in Chrome but not Firefox



function checkChild(val) {
alert(val);
//Child One
if (val == 1){
//Add code

  • What is onmousedown="this.value='';" supposed to accomplish? (it's what makes Firefox display an empty alert box)

  • This works in Firefox if I remove onmousedown="this.value='';". See this pen. A more maintainable solution might be to use addEventListener, like in this pen.

  • For what happens inside checkChild() Javascript has a construct called switch...case. Also I highly recommend dropping alert in favour of console.log for manual debugging.

  • @Patweb No, you're resetting the value to ''. This apparently happens before the onchange handler on Firefox, and after it on Chrome, hence the difference in behavior. My point is, why have the onmousedown handler in the first place? It does not "fetch the value" in any way, shape or form.

I would recommend not writing inline javascript. Instead add eventListener to your select:






var mySelect = document.getElementById('child');

mySelect.addEventListener('change', function(e) {

if (this.value == 1) {
console.log('val is 1');
} else if (this.value == 2) {
console.log('val is 2');
} else if (this.value == 3) {
console.log('val is 3');
} else if (this.value == 4) {
console.log('val is 4');
} else if (this.value == 5) {
console.log('val is 5');
} else {
console.log('val not specified');
}

});

<div class="check-now" style="width: 100%;">
<h1 class="cover-travel">Child(ren)</h1>
<select name="child" id="child">
<option value="0">None</option>
<option value="1">1</option>
<option value="2"> 2</option>
<option value="3"> 3 </option>
<option value="4"> 4 </option>
<option value="5"> 5 </option>
