如何将C＃代码值访问到javascript中？

Question

I have code like following

    function AddValidation() {
            var distance=@Utilities.getConfiguration(Configuration.DistanceUOM);

            $("#km").rules('add', { chekrule: ["#PerKm", "Cost Per " +distance +"should be positive."] });

}

I'm getting error for distance as undefined.

unable to get the proper value of @Utilities.getConfiguration(Configuration.DistanceUOM); in java script function

please correct me in syntax.

Answer 1

Now sure what kind of project you are using.

It could be

function AddValidation() {
            var distance="<%=ConfigurationManager.AppSettings["DistanceUOM"] %>";
            $("#km").rules('add', { chekrule: ["#PerKm", "Cost Per " +distance +"should be positive."] });

}

OR

function AddValidation() {
            var distance="@ConfigurationManager.AppSettings["DistanceUOM"]";
            $("#km").rules('add', { chekrule: ["#PerKm", "Cost Per " +distance +"should be positive."] });

}

depending on your mvc version.

Also you don't provide information what Utlilities is but if that code works in the code behind, it will also work on your view if you include the correct library at the top

<%@ Import Namespace="Ulities" %>

or

 @using Ulities

So if you include that library properly then you can use your thing:

function AddValidation() {
            var distance="<%= Utilities.getConfiguration(Configuration.DistanceUOM)%>";
            $("#km").rules('add', { chekrule: ["#PerKm", "Cost Per " +distance +"should be positive."] });

}

Can't help you more without knowledge of your project
