I don’t want any space before the input and after the input like " text" and "text " does not allow so I replace the white space but when we copy "text " from notepad and paste over the input and want to remove the space it throws error like "can not read property of undefined reading target".so how to do like when user give space front and back its automatically replace whitespace
const handleKeyDown = (e) => {
if (e.key === " ") {
e.preventDefault();
}
};
const handleChangeWhiteSpace = (e) => {
if (e.target.value.includes(" ")) {
e.target.value = e.target.value.replace(/\s/g, "");
}
};
<MyInput
type="text" style={{width:'240px'}}
error={formik.errors.input && formik.touched.input}
value={formik.values.input}
onBlur={formik.handleBlur}
onChange={(e)=>{formik.handleChange(e);handleChangeWhiteSpace()}}
onKeyDown={handleKeyDown}
name="input"
id="input"
autoFocus={false}
autoComplete="off"
/>
>Solution :
using regex the following should work, you can test it at regex101:
e.target.value = e.target.value.replace(/^[ \t]+|[ \t]+$/gm, "");
the cleaner solution would be what sojin suggested
e.target.value = e.target.value.trim()
