<script>
var words = new Array(); words[1] = 'fresh'; words[2] = 'ancient';
</script>
<script src="scripts/validation.js" type="text/javascript"></script>
Additionally, in the validation.js file, we find:
function checkValue(num){
alert(words[num]);
}
Is there a way to access the variable value? I keep encountering an error indicating the variable is not defined.
Great effort!
Here's how I handled my multi-language message:
To start, I created an array at the top of the page, close to the HEAD tag.
<script type="text/javascript">
var language = {};
</script>
Next, I populated the array with values retrieved from the database using a method that best suits your platform. In this case, I used ASP.NET MVC.
<script type="text/javascript">
language["greeting"] = '@Model.greeting';
language["farewell"] = '@Model.farewell';
//or you can assign values directly
language["hello"] = 'Hello';
language["goodbye"] = 'Goodbye';
</script>
<script src="javascript/translator.js" type="text/javascript"></script>
Finally, you can reference the array in your JavaScript file like so:
translate(“farewell”);
function translate(value){
alert(language[value]);
}
//Alternatively:
alert(language[“hello”]);
I hope this explanation proves helpful for you.
Avoid relying on global variables that are referenced across different files as it can lead to confusion for other team members or maintainers trying to understand the code. Instead, make sure to pass all necessary values to a function, which serves as documentation for what the function needs. Consider implementing the following approach:
<script src="javascript/validator.js" type="text/javascript"></script>
<script type="text/javascript">
var items = new Array('first', 'second');
checkItem(items, 0);
</script>
Inside validator.js:
function checkItem(arr, index){
alert(arr[index]);
}
