Autocomplete

[Sven]

Hi,

I have following code:

    //Autocomplete Gemarkungssuche
    $("#al_gemarkung").kendoAutoComplete({
        minLength: 1,
        dataTextField: "bez",
        select: onSelectAlkisplace,
        enable: true,
        dataSource: new kendo.data.DataSource({
           transport: {
               read: "mod_alkis/gem_search.php",
               //parameter
               parameterMap: function(options, operation) {
                   return {
                       placename: options.filter.filters[0].value
                   }
               }
           },
           schema: {
               data: "data"
           },
           //Filter aufServer nicht Client
           serverFiltering: true
       })
    });   

if I enter a letter everything works fine, but if I go back to the beginning of my input with the backspace key or delete everything in the input field I get the following error in the console:
TypeError: options.filter.filters[0] is undefined
How can I prevent this?

Thanks Sven

Hi Sven,

You could return the filter only if it has value. For example, if the filter is undefined, you could return empty string.

var placename = options.filter.filters.length > 0 ? options.filter.filters[0].value : ""
return {
placename: placename
}
