ajax

问题 I am making a web app, where I want to provide a search function. I am sending the searched name with an ajax request, and i want to pull the records of that particular person. But since there are many details that are to be displayed, I am finding it difficult to get the response. (I am not able to get more than one response at a time) I want to know, if there is a way to get multiple responses for a single request, or a way to send all my variables in the target PHP file to the requesting

问题 I am making an app that gets an array of news items from a remote source and displays them on a page. I have the endpoint, and can make a successful call, proven by console logs, using $.getJSON() . I placed this call into the parent component, because child components will need to use the data. However, when I pass this data down to a child component, the console error appears: Uncaught TypeError: Cannot read property 'headline' of undefined This is because React is trying to render the

问题 I'm trying to upload file using uploadhandler in Django. But it's returning the error: You cannot alter upload handlers after the upload has been processed Code: def upload_form(request): if request.method == 'POST': outPath = '/opt/workspace/jup2/juppro/uploads/23232' if not os.path.exists(outPath): os.makedirs(outPath) request.upload_handlers.insert(0, ProgressUploadHandler(request, outPath)) # place our custom upload in first position upload_file = request.FILES.get('file', None) # start

问题 I've implemented the Improved Persistent Login Cookie Best Practice for a "remember me" option. This works fine when requests are in sequence (traditional page loading). In this case you are sure that the next request will have the same series identifier and the token that was last sent by the server. But in the case of AJAX requests, where multiple requests are coming in parallel from the same browser, the first request will result in the generation of a new token number. But the other

问题 I have a textarea that is submitted with ajax that uses onbeforeunload to warn the user that they have not submit the textarea if they try to close the browser. The problem is I need to somehow clear the onbeforeunload within the success of the ajax submit so that onbeforeunload knows that the user has submitted the form successfully. Is there a way to clear the onbeforeunload with a line of code, similar to a clearTimeout or clearInterval? I'll show the onbeforeunload code I currently have

问题 I'm writing a SPA that uses underscore templating. The app searches for and rates music albums and returns the result via ajax.

问题 I am trying to use select2 with ajax loading. Here is my code: clonedTemplate.find('[id^=detailsPhaseFinanceMinor_]').select2({ placeholder: "Select", minimumInputLength: 1, ajax: { // instead of writing the function to execute the request we use Select2's convenient helper type: 'POST', contentType: "application/json; charset=utf-8", url: "mapBasic.aspx/GetFinSys", dataType: 'json', data: function (term, page) { return "{'term':\"" + term + "\"}"; }, results: function (data, page) { // parse
