In my Django app (using {% load crispy_forms_tags %}) I have a following dropdown menu:
<div id="div_id_report_division" class="form-group">
<label for="id_report_division" class=" requiredField">Test<span class="asteriskField"></span</label>
<div class="">
<select name="report_division" class="select form-control" required="" id="id_report_division">
<option value="" selected="">---------</option>
<option value="1">A</option>
<option value="2">B</option>
<option value="3">C</option>
<option value="4">D</option>
<option value="5">E</option>
</select> </div> </div>
I wish to remove option number 5 on page load. My Javascript on post.html with everything is:
<script type="text/javascript">
function on_load(){
/*
option 1.:
document.querySelector('id_report_division option[value=5]').remove();
option 2.:
var x = document.getElementById('id_report_division');
x.remove(5);
option 3.:
document.querySelector('#id_report_division option[value=5]').remove();
const first = document.querySelector("[id='id_report_division']");
*/
document.querySelector("[id='id_report_division' option[value=5]]").remove();
}
on_load();
</script>
How can I easly remove this option? It would be better if I could remove option where text is E, in case that value changes. But there will always be only one text 'E', no need to itterate.
You can iterate the select options list, check the inner text and remove like so:
var selectobject = document.getElementById("id_report_division");
for (var i=0; i<selectobject.length; i++) {
if (selectobject.options[i].text == 'E')
selectobject.remove(i);
}
