问题描述
当一个形式发布在我的控制器,我做以下检查:

if(ModelState.IsValid)
如果模型无效,错误将被添加到的ModelState
。然后,该模型被传递到与验证摘要视图。
If the model is not valid, errors are added to the ModelState
. The model is then passed to the view with validation summary.
不过,我想检查是否的ModelState
有从jQuery内就绪
处理错误,所以我可以添加一些额外的行为,如果表单有错误。这可能吗?
However, I want to check if the ModelState
has errors from inside the jQuery ready
handler, so that I can add some additional behavior if the form has errors. Is that possible?
推荐答案
您可以吐全局JavaScript变量:
You could spit global javascript variable:
<script type="text/javascript">
var isValid = @Html.Raw(Json.Encode(ViewData.ModelState.IsValid));
</script>
和则:
$(function() {
if (!isValid) {
alert('opa');
}
});
