Question

I have written code for javascript but it is not called any how. I tried to call both form html side and also by assigning attribute from page load event but it is not at all called.

This is the code for my javascript.

function rdbantiplatelet_onClick(thiscontrol, trName) {
    alert('hi');
    var RB1 = thiscontrol;
    var radio = RB1.getElementsByTagName("input");
    var trDose = document.getElementById(trName.toString());
//  var RB1 = document.getElementById("<%=this.rdbantiplatelet.ClientID%>");
//  var radio = RB1.getElementsByTagName("input");
//  var tblAntiplatelet = document.getElementById("<%=tblAntiplatelet.ClientID %>");

    for (var i = 0; i < radio.length; i++){
        if (radio[i].checked){
            trDose.style.display = "";
            return true;
        }
        else{
            trDose.style.display = "none";
            return true;
        }
    }
    return false;
    }

This is the code to call javascript written in page_load event..

rdbantiplatelet.Attributes.Add("OnClick", "return rdbantiplatelet_onClick(this,'" +  trDose.ClientID.ToString() + "');");

Answer 1

Try an alert() first to make sure your onclick is firing, then try your rdbantiplatelet_onClick() function:

rdbantiplatelet.Attributes.Add("OnClick", "alert('I am working');");
