Hi does anyone have any idea to make the input field behave like this example?
https://www.westpac.com.au/personal-banking/home-loans/calculator/mortgage-calculator/
we should not allow user to delete 0 and when user type should replace 0 with the value, and when we delete all the value, the cursor will always stays at the end of the first digit.
The below code should work the way you want it.
function theFunction(e) {
if (e.value <= 0) return e.value = 0
if (e.value[0] == 0) return e.value = e.value.substring(1)
}body{
width: 100vw;
height: 100vh;
}
.custom-input {
border-top-right-radius: 4px;
border-bottom-right-radius: 4px;
background-color: rgb(42, 46, 66);
color: rgb(249, 249, 251);
padding: 18px;
font-size: 48px;
height: 84px;
margin-bottom: 18px;
border-color: rgb(171, 175, 177);
}<body>
<input type="number" class="custom-input" id="custom-input" oninput="theFunction(this)" value="800">
</body>I think you can use the if condition in your handleChange function, for example :
...
var result = 0;
if(input <= 0 || input == ''){
result = 0;
} else {
result = event.target.value;
}
this.setState({
inputValue: result
})
...
Hope this will help you :)
