i'm currently working with rendering some graphs on a web mvc project. The graphs already render on my machine when i'm debugging the code, but the moment I publish it on the IIS of my QA server, I get the following error on console
TypeError: JSON.parse(...).forEach is not a function
Here's the a snippet of the code I'm currently working
ajaxPostConstancy.done(function (html) {
Utils.Alerts.HideGif();
var data = {};
var category = [];
var colors = [];
JSON.parse(html).forEach(function (e) {
category .push(e.date);
colors.push(e.color);
data[e.date] = e.data1;
})
....
any ideas of what's going on?
Edit: the html var inside the JSON.parse is te string returned by this code
public async Task<string> GetCompositionGraph(string contract, string methodName)
{
string preFormat = null;
try
{
string method = _configuration["Position:method:" + methodName];
PositionBL _bl = new PositionBL(Request, Response, _baseUri, method);
object model = await _bl.PostCompositionGraph(contract);
preFormat = JsonConvert.SerializeObject(model);
}
catch(Exception ex)
{
ViewBag.error = ex.Message;
}
return preFormat;
}
edit 2: the content of html variable which is generated by the code on the first edit:
html content:
[{"color":"#162ECB","date":"20","data1":1122954.8708},{"color":"#E03473","date":"00","data1":1323061.6168},{"color":"#CE029D","date":"26","data1":29982.2271}]
and this picture is the result I get from the JSON.parse when I debug my website
Edit 3: Visual input
The explorer console when the sites is deployed on my localhost for debugging
The explorer console while checking the site published on QA server
Edit 4: So i narrowed it down to the fact that the error comes when I debug the websit in Release mode, so that's kind of a step foward
If preformat returns null or an object forEach() will throw an error.
ajaxPostConstancy.done(function (html) {
Utils.Alerts.HideGif();
var data = {};
var category = [];
var colors = [];
var parsedDatas = JSON.parse(html)
if (Array.isArray(parsedDatas)) {
parsedDatas.forEach(function (e) {
// logic here
});
} else {
console.warn('This is not an array : ', html)
}
...
The forEach() method calls a function once for each element in an array while the JSON.parse() makes the html an object.

I am working on a Google Data Studio community connector, and I am trying to display only one field to start with. All of the code is in the code.gs file, except getAuthType() and isAdminUser() is in Auth.gs.
The issue is that once getData() is called, getFields() returns an empty object. Here is the log:
It looks like getSchema() is working correctly, here is the log from that function:
Here is the getFields() function:
function getFields() {
var fields = cc.getFields();
var types = cc.FieldType;
fields
.newDimension()
.setId('device')
.setName('Device')
.setType(types.TEXT);
return fields;
}
Here is getData():
function getData(request){
console.log('getData request', request);
request.configParams = validateConfig(request.configParams);
console.log('getFields()', getFields(), typeof getFields());
var requestedFields = getFields().forIds(
request.fields.map(function(field){
return field.name;
})
);
try{
console.log('start request');
var apiResponse = fetchDataFromApi(request);
var data = formatData(apiResponse, requestedFields);
}catch (e){
cc.newUserError()
.setDebugText('Error fetching data from API. Exception details: ' + e)
.setText(
'The connector has encountered an unrecoverable error. Please Try again later.'
)
.throwException();
}
return {
schema: requestedFields.build(),
rows: data,
}
}
getSchema():
function getSchema(request){
var schema = {schema: getFields().build()};
console.log(schema);
return schema;
}
The community connector is initialized outside of all functions in the same file:
var cc = DataStudioApp.createCommunityConnector();
I looked through the documentation, but I cannot find anything that would cause getFields() to return an empty object, based off what I have. Any thoughts?
I thought that getFields() returning an empty object was causing my app to display the fields incorrectly, but the issue was that the data I was passing to the app was in the incorrect format.
getFields() isn't useful until it is called with build() (i.e. getFields().build() )
I think it is expected behavior to receive an empty object for getFields() alone.
I am trying to write an application in C# using CefSharp. My intention is to fetch all the links on the given page eg,
https://wixlabs---dropbox-folder.appspot.com/index?instance=lp5CbqBbK6JUFzCW2hXENEgT4Jn0Q-U1-lIAgEbjeio.eyJpbnN0YW5jZUlkIjoiYjNiNzk5YjktNjE5MS00ZDM0LTg3ZGQtYjY2MzI1NWEwMDNhIiwiYXBwRGVmSWQiOiIxNDkyNDg2NC01NmQ1LWI5NGItMDYwZi1jZDU3YmQxNmNjMjYiLCJzaWduRGF0ZSI6IjIwMTgtMDEtMjJUMTg6Mzk6MjkuNjAwWiIsInVpZCI6bnVsbCwidmVuZG9yUHJvZHVjdElkIjpudWxsLCJkZW1vTW9kZSI6ZmFsc2V9&target=_top&width=728&compId=comp-j6bjhny1&viewMode=viewer-seo
When I load the page and open the dev tools and execute
document.getElementsByTagName('a');
in the dev tools I get 374 results. Next I execute the following code from BrowserLoadingStateChanged:-
private async Task ProcessLinksAsync()
{
var frame = browser.GetMainFrame();
var response = await frame.EvaluateScriptAsync("(function() { return document.getElementsByTagName('a'); })();", null);
ExpandoObject result = response.Result as ExpandoObject;
Console.WriteLine("Result:" + result);//What do I do here?
}
I get an expando object which seems to contain nothing. I am saying this because I used a break point and inspected the object. I have gone through https://keyholesoftware.com/2019/02/11/create-your-own-web-bots-in-net-with-cefsharp/ , https://github.com/cefsharp/CefSharp/wiki/General-Usage#javascript-integration and the questions on SO but was unable to solve my problem.
Am I doing something wrong here?
My actual intention is to fetch the links and then navigate to them.
Thanks in advance.
EDIT:
I used the following script in browser and dev tools both return 187 results which is correct.
(function() {
var links=document.getElementsByClassName('file-link');
var linksArray = new Array();
for (var i = 0; i < links.length; i++) {
linksArray[i] = String(links[i].href);
}
return linksArray;
})();
But in my application I get a 0 length array.
EDIT-2:
I used the following code to get the DOM:-
public void OnContextCreated(IWebBrowser browserControl, IBrowser browser, IFrame frame)
{
ContextCreated?.Invoke(this, frame);
const string script = "document.addEventListener('DOMContentLoaded', function(){ alert(document.links.length); });";
frame.ExecuteJavaScriptAsync(script);
}
For every other site I tried the code was successful except the URL mentioned above. Could any one possibly tell me what could be possibly wrong as the DOM is loaded in the dev tools and fully accessible. So, I guess something might be missing in my code.
Thanks again.
You need to wait for the page loads. Also if the page loads data using ajax, you need to wait a bit to data also load. Then you need to shape the result to a custom javascript object.
ChromiumWebBrowser browser;
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
browser = new ChromiumWebBrowser(
"https://google.com/"); // Tried with your URL.
browser.LoadingStateChanged += Browser_LoadingStateChanged;
browser.Dock = DockStyle.Fill;
Controls.Add(browser);
}
private async void Browser_LoadingStateChanged(object sender,
LoadingStateChangedEventArgs e)
{
if (!e.IsLoading)
{
await Task.Delay(5000); //Just for pages which use ajax loading data
var script = #"
(function () {
var data = document.getElementsByTagName('a');
return Array.from(data, a => ({href:a.href, innerText:a.innerText}));
})();";
var result = await browser.EvaluateScriptAsync(script);
var data = (IEnumerable<dynamic>)result.Result;
MessageBox.Show(string.Join("\n", data.Select(x=>$"{x.href}").Distinct()));
}
}
I've got a winforms app that has a ChromiumWebBrowser control and some basic windows controls. I want to be able to click a button, call javascript to get the value of a textbox in the browser, and copy the returned value to a textbox in the winforms app. Here is my code:
string script = "(function() {return document.getElementById('Email');})();";
string returnValue = "";
var task = browser.EvaluateScriptAsync(script, new { });
await task.ContinueWith(t =>
{
if (!t.IsFaulted)
{
var response = t.Result;
if (response.Success && response.Result != null)
{
returnValue = (string)response.Result;
}
}
});
txtTarget.Text = returnValue;
The result that comes back however is just "{ }". I've loaded the same web page in Chrome and executed the same javascript in the dev tools and I get the textbox value as expected.
The demo I looked at had sample code, simply "return 1+1;", and when I tried that I was getting the value "2" returned instead of "{ }". Interestingly, when I tried
string script = "(function() {return 'hello';})()";
I was still getting "{ }", almost as though this doesn't work with strings.
I've been scratching my head at this for a while and haven't been able to figure out how to solve this. Am I making a very basic syntax error or is there something more complicated going on?
So I think I've figured it out:
string script = "(function() {return document.getElementById('Email').value;})();";
string returnValue = "";
var task = browser.EvaluateScriptAsync(script);
await task.ContinueWith(t =>
{
if (!t.IsFaulted)
{
var response = t.Result;
if (response.Success && response.Result != null)
{
returnValue = response.Result.ToString();
}
}
});
txtTarget.Text = returnValue;
Removing the args object from EvaluateScriptAsync seemed to fix the issue. Not sure what the problem was - perhaps it was trying to run the javascript function with an empty args object when it shouldn't take any parameters?
Either way, it's resolved now.
public void SetElementValueById(ChromiumWebBrowser myCwb, string eltId, string setValue)
{
string script = string.Format("(function() {{document.getElementById('{0}').value='{1}';}})()", eltId, setValue);
myCwb.ExecuteScriptAsync(script);
}
public string GetElementValueById(ChromiumWebBrowser myCwb, string eltId)
{
string script = string.Format("(function() {{return document.getElementById('{0}').value;}})();",
eltId);
JavascriptResponse jr = myCwb.EvaluateScriptAsync(script).Result;
return jr.Result.ToString();
}
I am working to manage some Google Drive files with Google Apps Script. One piece of this project is reviewing properties on files, so I am using the Drive API rather than DriveApp. Additionally, Google Apps Script currently has access to the Drive REST API v2 instead of v3.
I've successfully set a property (id) and am able to pull the files with the property set.
console = Logger;
function Files (folderId) {
var optionalArgs,response
;
optionalArgs = {
q:'"'+folderId+'" in parents',
spaces:"drive"
}
do {
response = Drive.Files.list(optionalArgs);
response.items.forEach(function (file) {
console.log(file.properties);
var id = file.properties.find(function (property) {
return property.key === 'id';
});
this[id.value] = file;
},this);
} while (optionalArgs.pageToken = response.nextPageToken);
}
When running this function, I am able to see the file properties in the log
[{visibility=PUBLIC, kind=drive#property, etag="3GjDSTzy841RsmcBo4Ir-DLlp20/HGzJl78t8I2IehiAlaGXTkm2-C4", value=9e18766b-1cc9-4c1b-8003-b241f43db304, key=id}]
but get
TypeError :Cannot call method "find" of undefined.
I am unable to iterate through this resulting array. Using JSON.parse on it trys to convert it to an object, which is problematic for files with multiple properties. Using JSON.parse(JSON.stringify()) on it results in
SyntaxError: Unexpected token: u
which I understand is resulting from the value being undefined. I could work with that, if my log wasn't telling me otherwise.
"nextPageToken(string) The page token for the next page of files. This will be absent if the end of the files list has been reached."
Quote from: https://developers.google.com/drive/v2/reference/files/list#examples
so this line assigns an undefined value to optionalArgs.pageToken
while (optionalArgs.pageToken = response.nextPageToken);
and does not terminate the loop. A better way is to assign the value of optionalArgs.pageToken inside the loop and break the loop if its value is undefined like this:
console = Logger;
function Files (folderId) {
var optionalArgs,response
;
optionalArgs = {
q:'"'+folderId+'" in parents',
spaces:"drive"
}
do {
response = Drive.Files.list(optionalArgs);
response.items.forEach(function (file) {
console.log(file.properties);
var id = file.properties.find(function (property) {
return property.key === 'id';
});
this[id.value] = file;
},this);
// Assign the value inside the loop
optionalArgs.pageToken = response.nextPageToken
} while (optionalArgs.pageToken != undefined) // check to see if it undefined here and break the loop.
}
You can use v3 in Google Apps Script by selecting the version in the Advance Google Service option:
Just note that you have to follow how to request in Google Drive v3 but you can still use v2 because all of the example is still in v2.
Regarding your error, using their code in the sample code for Listing folders.
function listRootFolders() {
var query = '"root" in parents and trashed = false and ' +
'mimeType = "application/vnd.google-apps.folder"';
var folders, pageToken;
do {
folders = Drive.Files.list({
q: query,
maxResults: 100,
pageToken: pageToken
});
if (folders.items && folders.items.length > 0) {
for (var i = 0; i < folders.items.length; i++) {
var folder = folders.items[i];
Logger.log('%s (ID: %s)', folder.title, folder.id);
}
} else {
Logger.log('No folders found.');
}
pageToken = folders.nextPageToken;
} while (pageToken);
}
You can also read more code implementation of the above documentation.
Hope this helps.
My javascript:
var params = {};
params.selectedCurrency = 'USD';
params.orderIdForTax = '500001';
var xhrArgs1 = {
url : 'UpdateCurrencyCmd',
handleAs : 'text',
content : params,
preventCache:false,
load:function(data){
alert('success!');
},
error: function(error){
alert(error);
//the alert says 'SyntaxError: syntax error'
},
timeout:100000
};
dojo.xhrPost(xhrArgs1);
I tried debugging with firebug, i do get the appropriate response (i think). Here it is;
/*
{
"orderIdForTax": ["500001"],
"selectedCurrency": ["USD"]
}
*/
The comments /* and */ are somehow embedded automatically cuz the url im hitting with xhrPost is actually a command class on ibm's websphere commerce environment. Can anyone tell me what am i doing wrong here?
Server code
public void performExecute() throws ECException {
try{
super.performExecute();
double taxTotal;
System.out.println("Updating currency in UpdateCurrencyCmd...");
GlobalizationContext cntxt = (GlobalizationContext) getCommandContext().getContext(GlobalizationContext.CONTEXT_NAME);
if(requestProperties.containsKey("selectedCurrency"))
selectedCurrency = requestProperties.getString("selectedCurrency");
else
selectedCurrency = cntxt.getCurrency();
if(requestProperties.containsKey("orderIdForTax"))
orderId = requestProperties.getString("orderIdForTax");
OrderAccessBean orderBean = new OrderAccessBean();
cntxt.setCurrency(selectedCurrency.toUpperCase());
orderBean.setInitKey_orderId(orderId);
orderBean.refreshCopyHelper();
orderBean.setCurrency(selectedCurrency.toUpperCase());
orderBean.commitCopyHelper();
TypedProperty rspProp = new TypedProperty();
rspProp.put(ECConstants.EC_VIEWTASKNAME, "AjaxActionResponse");
setResponseProperties(rspProp);
}catch(Exception e){
System.out.println("Error: " + e.getMessage() );
}
}
The problem was with my client side code, weirdly.
load:function(data){
data = data.replace("/*", "");
data = data.replace("*/", "");
var obj = eval('(' + data + ')');
alert('Success');
}
Its weird but this worked. Lol.
I guess the problem is with coment-filtering option of handle as method.
The response should be comment filered as below.
See tha AjaxActionResponse.jsp (WCS)
vailable Handlers
There are several pre-defined contentHandlers available to use. The value represents the key in the handlers map.
text (default) - Simply returns the response text
json - Converts response text into a JSON object
xml - Returns a XML document
javascript - Evaluates the response text
json-comment-filtered - A (arguably unsafe) handler to preventing JavaScript hijacking
json-comment-optional - A handler which detects the presence of a filtered response and toggles between json or json-comment-filtered appropriately.
