<script type='text/javascript'>
function redirect() {
var input = document.getElementById('userInput').value;
switch(input) {
case 'ALCOA':
window.location.replace('alcoa-Forms.htm');
break;
case 'alcoa':
window.location.replace('/alcoa-Forms.htm');
break;
How do I make it so this function is not case sensitive so I can just write it once?
simplest way is to make the input all upper or all lower case. Take your pick:
input = input.toUpperCase();
switch (input) {
case 'ALCOA':
...
Keep in mind that this will also work for Alcoa
, aLcOa
, etc.
You could also just write case
twice:
switch (input) {
case 'ALCOA':
case 'alcoa':
make the input uppercase:
<script type='text/javascript'>
function redirect() {
var input = document.getElementById('userInput').value;
input = input.toUpperCase()
switch(input) {
case 'ALCOA':
window.location.replace('alcoa-Forms.htm');
break;
You need to convert your input to either lower or upper case. For example:
var input = document.getElementById('userInput').value.toLowerCase();
Use .toLowerCase() or .toLocaleLowerCase() Note that these functions are nearly identical with some obscure exceptions in languages such as Turkish.
function redirect() {
var input = document.getElementById('userInput').value.toLowerCase();
switch (input) {
case 'alcoa':
window.location.replace('alcoa-Forms.htm');
break;
}
}
A function is not "case sensitive". Rather, your code is case sensitive. The way to avoid this problem is to normalize the input to a single case before checking the results. One way of doing so is to turn the string into all lowercase before checking.
Use the case fallthrough syntax:
switch(text) {
case 'a':
case 'A':
doSomething();
}
Though .toLowerCase()
(or .toUpperCase()
) is the simplest way, there is also a regex way:
if (/^alcoa$/i.test(input)) {
// ...
}
if you use toUpperCase() then inside switch(input) function case string should be all in upper case like below:
var input = document.getElementById('userInput').value.toUpperCase();
switch (input) {
case 'ALCOA':
// do something
break;
}
if you use toLowerCase() then inside switch(input) function case string should be all in lower case like below:
var input = document.getElementById('userInput').value.toLowerCase();
switch (input) {
case 'alcoa':
// do something
break;
}
