Today, we need to generate an Option Record and insert it into the SELECT statement. The DOM method is different from the previous method.

By dom

// Use dom
$ ("Floatingfrequencycode"). Options. insertbefore (createoption (thestr, "01 "),
$ ("Floatingfrequencycode"). Options [0]);

// This method is required to generate optino
Function createoption (thetext, thevalue)
...{
VaR theoption = Document. createelement ("option ");
Theoption. innerhtml = thetext;
Theoption. value = thevalue;
Return theoption;
}

Function createoption (thetext, thevalue) not in Dom Mode)
...{
VaR theoption = Document. createelement ("option ");
Theoption. Text = thetext;
Theoption. value = thevalue;
Return theoption;
}

$ ("Floatingfrequencycode"). Options. Add (createoption (thestr, "01"), 0 );

// 0 indicates the insert position. If this parameter is not specified, it is directly appended to the end of the SELECT statement.
