I have been trying to cycle between the disability states of two inputs on my website by using a button attached to some JavaScript. My current code has two buttons in use which both disable one input and enable the other, however this is not very practical. I wanted to know how I can use one button and one script to cycle between the disability states of my inputs, this is my current code:
<script>
function switch_monthlyexpense()
{
document.getElementById("monthlyexpenses").disabled=false;
document.getElementById("monthlypexpenses").disabled=true;
}
</script>
<script>
function switch_monthlypexpense()
{
document.getElementById("monthlyexpenses").disabled=true;
document.getElementById("monthlypexpenses").disabled=false;
}
</script>
<button class="btn btn-primary" onclick="switch_monthlyexpense()" id="monthlyexpensestoggle">Expenses</button>
<button class="btn btn-primary" onclick="switch_monthlypexpense()" id="monthlypexpensestoggle">P Expenses</button>
<form id="expenses_form" style="visibility:visible;">
<div class="form-group">
<div class="form-group col-md-1">
<label for="monthlyexpenses" id="monthlyexpenseslabel">Monthly Expenses</label>
<input type="number" class="form-control" id="monthlyexpenses" placeholder="0" disabled>
</div>
<span class="input-group-text" id="dsign5">$</span>
</form>
<form id="pexpenses_form" style="visibility:visible;">
<div class="form-group">
<div class="form-group col-md-1">
<label for="monthlypexpenses" id="monthlypexpenseslabel">Monthly P Expenses</label>
<input type="number" class="form-control" id="monthlypexpenses" placeholder="0">
</div>
<span class="input-group-text" id="psign4">%</span>
</form>
disabled is an attribute so you can set it by:
document.getElementById("myId").setAttribute('disabled', '');
And to enable the element:
document.getElementById("myId").removeAttribute('disabled');
Your first function will look like:
function switch_monthlyexpense()
{
document.getElementById("monthlyexpenses").removeAttribute('disabled');
document.getElementById("monthlypexpenses").setAttribute('disabled', '');
}
<script>
// use a variable to note which one is disabled
let selected = "monthlyexpenses"
function switchDisabled () {
// toggle the from "monthlyexpenses" to "monthlypexpenses" or vice versa
selected = selected === "monthlyexpenses" ? "monthlypexpenses" : "monthlyexpenses"
// check if the DOM disabled state is the same as the selected
document.getElementById("monthlyexpenses").disabled = selected === "monthlyexpenses";
document.getElementById("monthlypexpenses").disabled = selected === "monthlypexpenses";
}
</script>
<button class="btn btn-primary" onclick="switchDisabled()" id="switch-button">Switch</button>
<form id="expenses_form" style="visibility:visible;">
<div class="form-group">
<div class="form-group col-md-1">
<label for="monthlyexpenses" id="monthlyexpenseslabel">Monthly Expenses</label>
<input type="number" class="form-control" id="monthlyexpenses" placeholder="0" disabled>
</div>
<span class="input-group-text" id="dsign5">$</span>
</form>
<form id="pexpenses_form" style="visibility:visible;">
<div class="form-group">
<div class="form-group col-md-1">
<label for="monthlypexpenses" id="monthlypexpenseslabel">Monthly P Expenses</label>
<input type="number" class="form-control" id="monthlypexpenses" placeholder="0">
</div>
<span class="input-group-text" id="psign4">%</span>
</form>
