Hello,

I am developing a small project using Asp.net MVC3. I would like to generate a random number using javascript and send this number to @Html.Editfor or @Html.TextBoxfor. I can generate random number but I cannot pass this value to html textbox to display.

My code is like that:
@using (Html.BeginForm())
{

            @Html.EditorFor(model => model.TrackingID)
            @Html.ValidationMessageFor(model => model.TrackingID)

}

Javascript:

Please help me.

Regards,
Shomen

Hi,

I solved this issue like this way...


             @Html.EditorFor(model => model.TrackingID, new { onclick="randomNumbers()"})

             @Html.ValidationMessageFor(model => model.TrackingID)


Javascript:

function randomNumbers() {
        // Math.floor(Math.random() * (UpperRange - LowerRange + 1)) + LowerRange; Geneate within a range
        var str = Math.floor(Math.random()*(2000 - 1000 +1)) + 1000;
        // var str1= document.getElementById('ZoneID').options[document.getElementById('ZoneID').selectedIndex].text; // To get text of selected item.
        document.getElementById('ZoneID').value = str;

}

But I will try what you said.

Thanks...

Try using Jquery..

function randomNumbers() {
        // Math.floor(Math.random() * (UpperRange - LowerRange + 1)) + LowerRange; Generate within a range
        var str = Math.floor(Math.random()*100);

        $("#TrackingID").val(str);

    }
