Having issues where in my .aspx page I pass in a boolean variable (C#) to a javascript function that is expecting a boolean type.
BUt the C# variable returns True, and javascript doesn't like the uppercase.
myjavascript( <%= MyBooleanVariableInCSharp %> );
If I convert the c# variable to string, then my javascript variable becomes a string and not a js bool value!
what is the solution to this nightmare? lol
Try this:
myjavascript( <%= MyBooleanVariableInCSharp.ToString().ToLower() %> );
if you need to do this often, just add this to the top of the javascript (or your js library file, etc.)
var True = true, False = false;
Then you code
myjavascript( <%= MyBooleanVariableInCSharp %> );
Would work just fine.
Another option if for whatever reason you don't want to use the variables is to write your javascript call like this:
myjavascript( '<%= MyBooleanVariableInCSharp %>'=='True' );
myjavascript('True' == 'True'), which doesn't require the use of variables. If you had myjavascript(<%= MyBooleanVariableInCSharp %> == 'True') in mind, the variables are required but it will never evaluate to true. Another idea based on yours: myjavascript('<%= MyBooleanVariableInCSharp %>' === '<%= bool.TrueString %>').
You could also do this.
myjavascript(<%=myBooleanVariableInCSharp ? "true" : "false" %>);
The other answers are targeting the old version, before Razor
if you are using Razor then this is the solution
myjavascript( @MyBooleanVariableInCSharp.ToString().ToLower() );
var myBoolInJavaScript = @Model.MyBoolInCSharp.ToString().ToLower(); worked like intended. Thank you for this answerfunction toBool(s){
return s==="True";
}
var b = toBool("@csharpvariable.ToBoolean()");
