当我关闭div时，如何将表单重置为原始状态
我正在使用ajax和django
一个建议是在我的表单中使用reset_recipe字段，如果设置为true将重置配方
这是我的disablePopup函数：
function disablePopup($contact_selector){
//disables popup only if it is enabled
if(popupStatus==1){
$("#backgroundPopup").fadeOut("fast");
$contact_selector.fadeOut("fast");
popupStatus = 0;
var form = $("form#createrecipeform");
console.log(form);
form.submit(function(e) {
e.preventDefault();
console.log('ajax form submission function called successfully.');
form = $(this);
console.log(form);
var serialized_form = form.serialize();
$.ajax({ type: "POST",
url: $(this).attr('action'),
data: serialized_form,
success: (function(data) {
console.log('ajax success function called successfully.');
data = $.parseJSON(data);
if (data.success) {
console.log('success');
var newForm = data.form;
form.replaceWith(newForm);
} else {
console.log('failure');
var newForm = data.form;
form.replaceWith(newForm);
}
})
});
return false;
});
}
}
这是我使用
创建配方的视图def createrecipe(request):
print "entering createrecipeview"
if request.method == 'POST':
print "form is a post"
form = RecipeForm(request.POST)
if form.is_valid():
print "form is valid"
form = RecipeForm(initial = {'original_cookbook' : request.user.cookbooks.all()[0]})
form = form.save()
if form.cleaned_data['reset_recipe'] == "True"://here is the line that uses the reset_recipe function but right ow it is not working
print "reset recipe"
form = RecipeForm(initial = {"original_cookbook": request.user.cookbooks.all()[0]})
t = loader.get_template('cookbook/create_form.html')
c = RequestContext(request, {
'form': form,
})
data = {
'replace': True,
'form': t.render(c),
'success': False,
}
json = simplejson.dumps(data)
return HttpResponse(json,mimetype='text/plain')
t = loader.get_template('cookbook/create_form.html')
c = RequestContext(request, {
'form': form,
})
data = {
'replace': True,
'form': t.render(c),
'success': True,
}
json = simplejson.dumps(data)
return HttpResponse(json, mimetype='text/plain')
else:
print "form is invalid"
form = RecipeForm(request.POST)
t = loader.get_template('cookbook/create_form.html')
c = RequestContext(request, {
'form':form,
})
data ={
'form': t.render(c),
'success': False,
}
json = simplejson.dumps(data)
return HttpResponse(json, mimetype='text/plain')
现在，当我尝试关闭div时，它会重定向到一个页面并给我以下代码：
{"success": false, "form": "<form action=\"/cookbook/createrecipe/\" method=\"POST\" id=\"createrecipeform\">\n\t<table>\n\t\t<div style='display:none'><input type='hidden' name='csrfmiddlewaretoken' value='3fb6b9952f50edbe7654666ef20a6900' /></div>\n\t\t<tr><th><label for=\"id_name\">Name:</label></th><td><ul class=\"errorlist\"><li>This field is required.</li></ul><input id=\"id_name\" type=\"text\" name=\"name\" maxlength=\"200\" /></td></tr>\n<tr><th><label for=\"id_author\">Author:</label></th><td><ul class=\"errorlist\"><li>This field is required.</li></ul><input id=\"id_author\" type=\"text\" name=\"author\" maxlength=\"100\" /></td></tr>\n<tr><th><label for=\"id_picture\">Picture:</label></th><td><input type=\"file\" name=\"picture\" id=\"id_picture\" /></td></tr>\n<tr><th><label for=\"id_ingredients\">Ingredients:</label></th><td><ul class=\"errorlist\"><li>This field cannot be null.</li></ul><textarea id=\"id_ingredients\" rows=\"10\" cols=\"40\" name=\"ingredients\"></textarea></td></tr>\n<tr><th><label for=\"id_steps\">Steps:</label></th><td><ul class=\"errorlist\"><li>This field cannot be null.</li></ul><textarea id=\"id_steps\" rows=\"10\" cols=\"40\" name=\"steps\"></textarea></td></tr>\n<tr><th><label for=\"id_prep_time\">Prep time:</label></th><td><ul class=\"errorlist\"><li>This field is required.</li></ul><input type=\"text\" name=\"prep_time\" id=\"id_prep_time\" /></td></tr>\n<tr><th><label for=\"id_type\">Type:</label></th><td><ul class=\"errorlist\"><li>This field is required.</li></ul><select name=\"type\" id=\"id_type\">\n<option value=\"\" selected=\"selected\">---------</option>\n<option value=\"SW\">Sandwich</option>\n<option value=\"AP\">Appetizers</option>\n<option value=\"SD\">Sauces and Dressings</option>\n<option value=\"SS\">Soups and Salads</option>\n<option value=\"VG\">Vegetables</option>\n<option value=\"RG\">Rice, Grains and Beans</option>\n<option value=\"PA\">Pasta</option>\n<option value=\"BR\">Breakfast</option>\n<option value=\"MT\">Meat</option>\n<option value=\"SF\">Seafood</option>\n<option value=\"BP\">Bread and Pizza</option>\n<option value=\"DT\">Desserts</option>\n</select><input type=\"hidden\" name=\"reset_recipe\" value=\"False\" id=\"id_reset_recipe\" /></td></tr>\n\t</table>\n\t<p><input type=\"submit\" value=\"Submit\"></p>\n</form>"}
需要注意的另一件事是页面重定向到表单操作页面
抱歉这么多代码但似乎都很相关

$("#createrecipeform").attr('reset_recipe', "True");
只会向表单元素添加一个属性：
<form reset_recipe="True" id="createrecipeform">
您需要在名为reset_recipe的表单中添加一个输入元素。
在表单中添加隐藏字段：
reset_recipe = forms.CharField(widget=django.forms.widgets.HiddenInput, required=False)
并将其值设置为True（而不是向表单添加属性）：
$("#id_reset_recipe").val("True");
看起来您只是提交表单（没有AJAX）：
$("#createrecipeform").submit();
您需要通过XHR提交：
$("#createrecipeform").submit(function(event){
/* stop form from submitting normally */
event.preventDefault();
/* get form field values */
var serialized_data = $( this ).serialize();
/* Send the data using post and put the results in the form */
$.post( url, serialized_data,
function( data ) {
$("#createrecipeform").replace( data.form );
}
);
});
也为json使用正确的mime类型：
return HttpResponse(json, mimetype='application/json')
但如果您只想重置表单，通常可以使用：
$("#createrecipeform").reset()
