function submit(){ if($(newtitle).value == "" || $(relationartic).value=="" ||$(tipssep).value==""||$(blackpic).value==""||$(picflag)==""||$(friedlytips).value == "" ||$(frendly_isuse).value ==""||$(new_isuse)==""||$(frontset)==""||$(colorset).value=="") { alert("请完整填写信息！") ; return false ; } else { alert ("123") ; }} function $(str){ return "document.getElementById(str)";}为什么我点击提交，js却没控制
[解决办法]
类似$(newtitle).value ===> $("newtitle").value
return "document.getElementById(str)"; ===> return document.getElementById(str);
[解决办法]
function sub()
{
var newtitle = $("#newtitle").val();
var relationartic = $("#relationartic").val();
var tipssep = $("#tipssep").val();
var blackpic = $("#blackpic").val();
var picflag = $("#picflag").val();
var friedlytips = $("#friedlytips").val();
var frendly_isuse = $("#frendly_isuse").val();
var new_isuse = $("#new_isuse").val();
var frontset = $("#frontset").val();
var colorset = $("#colorset").val();
if(newtitle== ""||relationartic=="" ||tipssep==""||blackpic==""||picflag==""||friedlytips=="" ||frendly_isuse==""||new_isuse==""||frontset==""||colorset=="")
{
alert("请完整填写信息！") ;
return false ;
} else
{
alert ("123") ;
}
}
把事件的名称换下应该可以吧
