我已经创建了一个django脆的形式.我想隐藏提交按钮，直到每个字段都已输入我发现一些使用jQuery的解决方案，但它是不显示提交按钮后，输入每个字段，我需要你的帮助，以进一步进行.
我已经添加了两个图像，隐藏提交按钮，并尝试jquery之前，

在尝试jquery后，即使输入每个字段，提交按钮也不可见。

下面是我的代码为各自的文件，
forms.py

class AppForm(forms.ModelForm):
    
        class Meta:
            model = App
            fields = ('__all__')
        def __init__(self, *args, **kwargs):
            super(AppForm, self).__init__(*args, **kwargs)
            self.helper = FormHelper()
            self.helper.form_show_labels = False
            defualt_image_path = '/media/photo.png'
            self.fields['appicon'].widget.attrs['placeholder'] = defualt_image_path
            self.fields['appicon'].widget.attrs['classs']= 'appicon-field'
            self.fields['appname'].widget.attrs.update({'placeholder': 'Apps Name', 'class':'appname-field'})
            self.fields['link'].widget.attrs.update({'placeholder':'App Link','class':'link-field'})
            self.fields['category'].widget.attrs.update({'placeholder':'App Category', 'class': 'catg-field'})
            self.fields['subcategory'].widget.attrs.update({'placeholder':'Sub Category', 'class': 'subcatg-field'})
            self.fields['points'].widget.attrs.update({'placeholder':'ADD POINTS', 'class': 'points-field'})

字符串

$(document).ready(function() {
  // Function to check if all fields are filled
  function checkFields() {
    var imageInput = $('.appicon-field')[0].files.length > 0;
    var charInput1 = $('.appname-field').val().trim() !== '';
    var charInput2 = $('.link-field').val().trim() !== '';
    var charInput3 = $('.catg-field').val().trim() !== '';
    var charInput4 = $('.subcatg-field').val().trim() !== '';
    var charInput5 = $('.points-field').val().trim() !== '';
    // Show/hide submit button based on input status
    document.querySelector('.submitform-button').style.display = imageInput && charInput1 && charInput2 && charInput3 && charInput4 && charInput5 ? 'inline-block' : 'none';
  }
  // Trigger checkFields on input change
  $('.appicon-field, .appname-field, .link field, .catg-field, .subcatg-field, .points-field').on('change', function() {
    checkFields();
  });
  // Initial check on page load
  checkFields();
});
