在代码隐藏中调用JavaScript

Question

I am calling javascript via codebehind. Giving object expected error. How can I pass some value through ShowDialog() function?

here is my code in codebehind

ClientScript.RegisterStartupScript(GetType(), "Call my function", "ShowDialog("Value_here");", true);

and in my javascript

    <script type="text/javascript">
    var IRProjectID = 0;

    function ShowDialog(UnitID) {
        radconfirm("Are you sure you want to approve this Help Desk item?", confirmBackChecked);
        IRProjectID = UnitID;
    }

    function confirmBackChecked(arg) {
        if (arg == true) {
            __doPostBack(IRProjectID, 'Approve');
        }
    }
    </script>

Answer 1

ClientScript.RegisterStartupScript(this.GetType(), "Call My Function", "ShowDialog("Value_here");", true);

Answer 2

尝试这个

ClientScript.RegisterStartupScript(this.GetType(), "Test", "ShowDialog("+Value_here+");", true);

Answer 3

Perhaps your calling a javascript function too soon... Try with Page.RegisterClientScriptBlock

Be carefull when you call javascript function. Be sure that it exist before!!!.

Edit :

Page.RegisterClientScriptBlock is obsolete, use ClientScriptManager.RegisterClientScriptBlock

Answer 4

I think the error is thrown by the double quotes you use around Value_here

ClientScript.RegisterStartupScript(GetType(), "Call my function", "ShowDialog("Value_here");", true);

try this

ClientScript.RegisterStartupScript(GetType(), "Call my function", "ShowDialog(\"Value_here\");", true);

or

ClientScript.RegisterStartupScript(GetType(), "Call my function", "ShowDialog('Value_here');", true);
