it's a easy essay about the difference in Response.Write、 ClientScript.RegisterStartupScript、 ClientScript.RegisterClientScriptBlock.
code1:
string message="I have a test now";
StringBuilder sb = new StringBuilder();
sb.Append(" <script type=\"text/javascript\"> \n ");
sb.Append(" alert(\"" + message + "\") \n");
sb.Append(" </script> \n");
Response.Write(sb.ToString());
code2:
string function = string.Format("alert('{0}')", message);
ClientScript.RegisterStartupScript(this.GetType(), "onclick", function, true);
code3:
string function = string.Format("alert('{0}')", message);
ClientScript.RegisterClientScriptBlock(this.GetType(), "onclick", function, true);
as you konw ,these three code3 have a the same funtion .
if you have a test,you will find the differece in them. Actually, the code1 block is equal with code3 block .
but the code3 block can help you to improve User Experience,if you don't use the ajax in your solution.
it's also a dev log for someone who need it.
BTW,
the differece in ClientScript.RegisterStartupScript and ClientScript.RegisterClientScriptBlock:
ClientScript.RegisterClientScriptBlock adds javascript function block at the right endings of "<form runat="server">" tag of web form.
and ClientScript.RegisterStartupScript just appends it above "</form>".
what about Response.Write? you can figure it out.
or what about just design a demo about it.
