Actually I need a method which have same error message in javascript validation (client side) and in my django form validation (server side).

I search for any django library for this but I didn't find any. This is the most relative question I founded in SO, but it seems not helpful:

Django Javascript form validation

Do you know any django library for this or if not what is the best method to do this?

Thanks in advance.

我找不到任何现有的库来轻松地做到这一点，所以我使用了一种解决方法。

Django 表单错误采用列表格式。将 dict 列表从 Django 转移到 JS 很困难。我有一个派上用场的功能。此函数(convertErrorsToDict)将每个参数的所有错误连接在一起成为 1 个错误。：

视图.py：

def convertErrorsToDict(errors): #previously errors={f1:[er1]}. make it {f1:'er1'} so we can render nicely
    #converts form errors from list to dictionary
    errors2={}
    for f in errors:
        errors2[f]='.'.join(errors[f])
    return (errors2)


def setPassword(request):
    your_form=FormName();
    context={}
    errors=convertErrorsToDict(your_form.errors)
    context['errors']=errors;
    return render(request,'htmlFileName.html',context)

文件名.html：

{% load jsonify %}
<script type="text/javascript">
    var errors={{errors|jsonify}};    
</script>

FileName.js 在 js 文件中我们现在可以直接errors作为变量使用。

console.log(errors.para1) //para1 is first para in the form. eg first_name
console.log(errors.para2)

当我们需要完全控制表单错误内容时，此功能很有用。
