});
var weekList = $(".weekList").children();
$("#week_appoint").click(function(){
if(this.checked){
weekList.eq(0).change();
}
});
weekList.change(function() {
var week_appoint = $("#week_appoint").prop("checked");
if (week_appoint) {
var vals = [];
weekList.each(function() {
if (this.checked) {
vals.push(this.value);
}
});
var val = "?";
if (vals.length > 0 && vals.length < 7) {
val = vals.join(",");
}else if(vals.length == 7){
val = "*";
}
var item = $("input[name=v_week]");
item.val(val);
item.change();
}
});
});
效果图如下：
