Select initialization adds the option to give the Echo value through the label, because the Echo value and the initialization value in option have a value repeat, deduplication, and so on!

/**

Hour This function method is not well organized, the interface is to refer to this method, but it is very easy to understand, go back to the next time you can refer to the following, the emphasis on remembering the tag element is not obtained by ID to use this selectObj.options.add (Val,  val)); Otherwise use append, don't use appendchild

Function Hour () {
var a=$ ("#sltid"). Find ("option:selected"). Val ();
var sltid= $ (". Sltid");
var sltids= $ (". Sltids");
for (var i = 0; I <=24; i++)
{

var opt = document.createelement ("option");
if (i<10) {
Opt.value = "0" +i;
Opt.innertext = "0" +i;
} else{
Opt.value =i;
Opt.innertext = i;
}

Sltid.append (opt);
}

for (var j = 0; J <=60; J + +)
{
var opts = document.createelement ("option");
if (j<10) {
Opts.value = "0" +J;
Opts.innertext = "0" +J;
} else{
Opts.value =j;
Opts.innertext = j;
}
Sltids.append (opts);
}
}
