Add required attribute to all inputs. I’m not confident in code style, but as a logical example:
<input ... name="account_number" required="{{school_role === 1}}" ... />
Solution 1 :
Solution 2 :
- Add
</div>to each section - Give each div a class of hide
- Toggle the hide on change of the select
- toggle the required
const ifs = [...document.querySelectorAll("[id^=if]")];
document.getElementById("school_role").addEventListener("change", function() {
const val = this.options[this.selectedIndex].textContent;
ifs.forEach(ifDiv => {
ifDiv.classList.toggle("hide", !ifDiv.id.includes(val))
const input = ifDiv.querySelector("input");
if (ifDiv.classList.contains("hide")) input.removeAttribute("required")
else input.setAttribute("required", true)
});
}).hide {
display: none;
}<div class="select">
<select name="school_role" id="school_role" required>
<option value="">--------</option>
<option value="1">Student</option>
<option value="2">Academic</option>
<option value="3">Employee</option>
</select>
</div>
<form>
<div id="ifStudent" class="hide">
<label class="label">Account number</label>
<input class="input" type="text" name="account_number" value="" placeholder="Account number">
<div class="help is-danger">

</div>
<div id="ifEmployee" class="hide">

<div class="help is-danger">
{% for error in academicForm.academic_number.errors %}{{ error }}{% endfor %}
</div>
</div>
<input type="submit">
</form>Problem :
My html file has a select, with three different options. If you select one it will display different inputs depending on what option you choose, but these inputs are required by default, and I can’t send the form if I don’t fill all the inputs.
function yesnoCheck(that) {
if (that.value == "1") {
document.getElementById("ifStudent").style.display = "block";
} else {
document.getElementById("ifStudent").style.display = "none";
}
if (that.value == "2") {
document.getElementById("ifAcademic").style.display = "block";
} else {
document.getElementById("ifAcademic").style.display = "none";
}
if (that.value == "3") {
document.getElementById("ifWorker").style.display = "block";
} else {
document.getElementById("ifWorker").style.display = "none";
}
}<div class="select">
<select onchange="yesnoCheck(this);" name="school_role" required>
<option value="">--------</option>
<option value="1">Student</option>
<option value="2">Academic</option>
<option value="3">Employee</option>
</select>
</div>
<div id="ifStudent" style="display: none;">
<label class="label">Account number</label>
<input class="input" type="text" name="account_number" value="{{ studentform.account_number.value }}" placeholder="Account number">
<div class="help is-danger">
{% for error in studentForm.account_number.errors %}{{ error }}{% endfor %}
</div>
<div id="ifEmployee" style="display: none;">
<label class="label">Employee Number</label>
<input class="input" type="text" name="employee_number" value="{{ employeeForm.employee_number.value }}" placeholder="Employee number">
<div class="help is-danger">
{% for error in employeeForm.employee_number.errors %}{{ error }}{% endfor %}
</div>
<div id="ifAcademic" style="display: none;">
<label class="label">Academic number</label>
<input class="input" type="text" name="academic_number" value="{{ academicForm.academic_number.value }}" placeholder="Academic number">
<div class="help is-danger">
{% for error in academicForm.academic_number.errors %}{{ error }}{% endfor %}
