I have an angular controller that takes data from a form, manipulates the data and sends it to the server via $http to be saved
The issue is that the code works fine sometimes i.e it returns the success function and doesn't work sometimes i.e it returns error code 0 but even when this happens the data is still being saved in the database even the server log shows that its returning success, why is this? The success function is called sometimes and sometimes the error one is called. What am I doing wrong?
The angular controller is:
app.controller("premiumAdvertsController",function($scope,ergastAPIservice,$routeParams,$location,$rootScope)
{
function uploadImage(input,success) {
console.log("yeh input hai ",input);
if ( input.files && input.files[0] ) {
var FR= new FileReader();
FR.onload = function(e) {
success(e.target.result);
};
FR.readAsDataURL( input.files[0] );
}
}
$scope.registerPremiumAdvertisement=function()
{
console.log("shakil k sath check!eeersss!");
console.log("hello");

});the code for the $http function (saveHotbrand) is :
ergastAPI.saveHotBrand=function(abc)
{
return $http({
method:'POST',
url:'/saveAdd',
data:abc
})
}
app.post('/saveAdd',function(req,res){
console.log("save add request!");
var collection=req.db.get("advertisements");
console.log("got database")
collection.insert(req.body,function (err,doc){
if(err)
{
console.log("sending error")
res.send({error:true});
}
else {
console.log("sending success")
res.send({success:true});
}
})

Try this in the nodejs code:
app.post('/saveAdd',function(req,res){
var collection=req.db.get("advertisements",function(err){
collection.insert(req.body,function (err,doc){
if(err)
{
res.send({error:true});
}
else {
res.send({success:true});
}
})
})
})
I had faced a similar problem which was resolved by adding a callback function. You can see the question here.
答案 1 :(得分：0)
将您的eargast呼叫功能更改为此 ergastAPIservice.saveHotBrand（F）.success（函数（RES）{ }
然后它才会成功。
答案 2 :(得分：0)
您通过单击按钮提交表单并处理其单击事件以提交表单，无论何时执行此操作，您都需要从onCLick函数返回false。
答案 3 :(得分：0)
根据this页面，错误代码0实际上是成功的代码，它只是导致问题的if条件。包括对0的检查，它应该有效。
答案 4 :(得分：0)
因此对于任何人来说，页面基本上都被重定向，所以我开始通过ng-click而不是ngsubmit来调用控制器功能，并且它可以工作。
