</script>
<script>
//Demo
layui.use('form', function(){
var form = layui.form;
var $ = layui.jquery;
//监听提交
form.on('submit(formDemo)', function(data){
/* layer.msg("提交之前"); */
$.ajax({
type: 'post',
url: '/servlet/write_weeklyServlet',
dataType:'json',
data: data.field,
success: function (res) {
layer.msg("提交成功");
if (res.code==0) {
layer.close(layer.index);
window.parent.location.reload();
} else {
layer.alert(res.msg, {icon: 5}, function () {
});
}
},error:function (result) {
layer.msg("提交失败");
}
});
/* 显示输入的信息*/
layer.msg(JSON.stringify(data.field));
return false;
});
});
</script>
</body>
</html>
大佬们，一直提交失败，怎么解决？
有什么可能元原因呢？
