I am working on a project with asp.net and vb.net language system.
Now I made a table on the asp file, and before clicking on a button "update", by JavaScript, I would like to get all the string data written in the text boxes each placed inside a cell of the table.

Now, I wrote the following codes;

function getData(){
        var tblData = new Array();          
        var table = document.getElementById("<%=tblA.ClientID%>");
        var i;
        var txt;
        var txt2;

        tr = table.getElementsByTagName('tr');
        for (i = 0; i < tr.length; i++) {
            var ttl = "txt : ";
            var ttl2 = "txt2 : ";

            td = tr[i].getElementsByTagName('td');
            txt = td[4].childNodes[0].nodeValue; //This is wrong...
            txt2 = td[10].childNodes[0].nodeValue; //This is wrong...
            alert(ttl + txt + ttl2 + txt2);

            tblData[i, 1] = txt;
            tblData[i, 2] = txt2;
       // Here, I would like to send the array object containing the data of the textboxes. How can I do it?
        return true;

Now, please let me know what to wrote to get the texts from the textboxes, and how to send the array data to the server for update_click function to get it.

Shouldn't this be in the ASP forum? If you want help with JS just post some of the pure HTML, not ASP/VB


Im not sure if this is exactly what you need.
But this will help you to get your things done.
