I have this JS function in my .cshtml file. I need to pass the string from the C# Object to a JavaScript variable so that I can display the ReceiverName as an alert. I am kinda new to ASP.NET so I'm not quite sure whether this is the best way as C# and JS will have to be used together. Does anyone know a better approach as I am quite lost? This is my 1st question here so please if there's any more info required I'll be glad to answer : )
function autoFillForeign(){
@{
string custID = (string)ViewData["customerID"];
PayeeListDAL payeeContext = new PayeeListDAL();
List<PayeeList> payeeList = payeeContext.GetAllPayeeList(custID);
ViewData["name1"] = payeeList[0].ReceiverName;
@: alert(@ViewData["name1"])
}
}
I didn't quite get what you want to achieve but it is easy to pass values from C# to JavaScript. You can try out these approaches...
<script type="text/javascript">
function autoFillForeign(){
var msg = "@msg";
alert(msg);
}
</script>
and the C# variable might be declared any where above that function like below:
@{
string msg = "You are learning good";
}
Sometimes you might even want to get a value from C# function into JavaScript function, its still the same approach.
<script type="text/javascript">
function autoFillForeign(){
var msg = "@ShortenText(msg)";
alert(msg);
}
</script>
Your C# code might look something like below:
@functions{
public string ShortenText(string txt)
{
return (txt.Length > 10)? txt.Substring(0, 10): txt;
}
}
and your c# variable might be declared like
@{
string msg = "I am not a new C# programmer; I started programming C# since 2016";
}
