问题 My client has a huge list of contacts. I created a form with a scrolling list, in order to select a contact. The issue is that the scrolling list is too long. Is there a way (and if so, how?) for my client to start typing the first letters of a contact name, so the 'field area' (or other) fills in automatically the correspondant contact name? Thank you in advance for your help. Kind regards, 回答1: You can load the select with this javascript: function updateSelect(vA) { var select = document

问题 I have searched many other threads about this and I can't see what I am doing wrong, I am trying to send form values to a php file to send as an email, however the pages always refreshes. I have tried using event.preventDefault and return false both before and after my ajax call but none seem to work. What am I missing here here is my code. HTML <form method="post" name="registerForm" class="form"> <label for="fullName" class="form__fullname form__label">Full Name</label> <input type="text"

问题 Is it possible to put ("xxxxx").html(data) in a for loop where the "xxxx" variable changes each time? I honestly feel like I've tried everything. I'm trying to fill up an HTML table with JSONP data from a looping ajax call where the URL changes each time. The same callback function is used every time, but, obviously, I keep overwriting the data that is to be sent to the HTML table tags because I can't figure out a way to dynamically change these variables. Basically, I want the first time the

问题 hi I want to build a control panel for a web art application that needs to run in fullscreen, so all this panel, that controls stuff like colors and speed values, have to be located at a different window. My idea is to have a database storing all these values and when I make a change in the control panel window the corresponding variable in the application window gets updated too. So, it's basically a real-time update that I could do with AJAX setting a interval to keep checking for changes
