问题 There's a very simple website containing just a few elements of which I'd like to retrieve a table. Previously I've used file_get_contents('http://www.example.com') for this exact purpose and extracted the piece of information I needed through explode and str_replace commands, which worked fine. However, this website requires POST data before it will display the table I require. I know only the name and id of the select boxes through which the data is submitted, as well as the 'option value'

问题 I have implemented JQuery FullCalendar by fetching the events dynamically from an aspx page. But it is not displaying the events on the calendar. But if I manually add the page response to the events attribute, it works fine. Can anybody please help what would be the issue? Here is my code. $('#calendar').fullCalendar({ theme: true, header: { left: 'prev,next today', center: 'title', right: 'month,agendaWeek,agendaDay' }, //events: "GetCalendarEvents.aspx?id=2612&role=supervisor" --->not

问题 I will admit php is a new language to me. Now I can get each of these working individually. In my prepare query SELECT * FROM... will allow my PDO fetch assoc while loop to work, but then fetch column doesn't work. And then I use SELECT COUNT(*) my fetch column works but then my fetch assoc doesn't. So Is there away around this so both will work? As I need the fetch column to return how many rows there are as an integer value (1 or 0) to determine if the user has entered log in information.

问题 I'm trying to use fetch to get a json object, and this does work correctly. Then I'm assigning a string based on the data and want to use that string in the ssml response...doing it the way I have it now it is about 300 ms too slow and the var is undefined, if I try to place the ssml response elsewhere in this code it comes up with an error "No response has been set". Can anyone point me in the right direction, I've literally been on this issue for 5 days in a row (already gave up on

问题 I'm building a SignUp form and have the following API call to POST the form: const request = new Request('http://localhost:4300/auth/', { method: 'POST', headers: new Headers({ 'Accept' : 'application/json', 'Content-Type' : 'application/json', }), body: JSON.stringify({ user: data }) }); fetch(request).then(response => { console.log(response); const auth = response.headers.get('Authorization'); console.log(auth) }); The problem is response.headers.get('Authorization') is returning as null .

问题 This question already has answers here : Can scripts be inserted with innerHTML? (18 answers) Closed last year . I was experimenting with getting a fragment of HTML using the fetch API, and then adding it to an HTML page. While this works fine for HTML content, I noticed that if I put a <script> tag in the fragment, the tag isn't stripped out, but it also isn't executed. Below is an example. I would expect the alert to fire, but it doesn't, even though the script tag appears on the page. My

问题 So, I am a total n00b at PHP (and back-end programming in general), but I never the less decided I wanted to build a functioning database that users could search client-side as th final project for my first web dev class. Anyway, I made my site and database on a localhost, and though it took a while, I got everything functioning perfectly. When I tried to move it to my webhost, however, everything started breaking because, previously unbeknownst to me, the webhost is using PHP 5.2. I've been

问题 Thank you for taking the time to read this and I will appreciate every single response no mater the quality of content. :) I'm trying to create a php script which searches a text file for specific text. A person types in the specific text within a HTML form and the php script should search for that specific text within the text file. The value of the input field of the HTML form is "username" and within the php document, the variable "$username" is the entered data, example shown below:
