问题 I have a page on my site that is setup for recurring payments, but I want to disable the PayPal checkout buttons until someone has checked the box that agrees to my Terms Of Service. Can you help me figure out how to do this properly? THANKS!!!!! -Brad 回答1: I'm not gonna give you a full answer written in code because I don't know the elements or variable names in your code.

问题 I would like to know what is the best way to create next/previous buttons for an entry in the database. Let's say we have a table with images and every image has an ID and a Path. If the current image has ID equal to "9" how can I get the next and the previous IDs? I already found a solution for this right here https://stackoverflow.com/a/8874382 but this seems to be the latest choice. If we have over 10000 entries (images) in our database, this will overwhelm the server. First of all, it

问题 The application is a step sequencer application with 16 radio groups with 8 buttons in each group. It works perfectly except once a group has a button selected I cant turn it off unless I use the clear button I have created to clear all radiogroups. What I would like to add is some code that says when a selected radio button is selected again it simply turns off like a toggle. I tried using toggles but then other issues arose with that method. Below are two attempts but both simply stops me

问题 I have a really really really strange issue here. I have this line of code: SeekBar mProgressBar = (SeekBar) findViewById(R.id.SeekBar); And it throws a ClassCastException: android.widget.Button as the title indicates.

问题 I'm experiencing some troubles using mnemonic keys in Windows Forms : Simply having a form with a button, which uses ALT+s as the accelerator: this.searchButton = new System.Windows.Forms.Button(); this.searchButton.Text = "&search"; The button action is executed by simply pressing "s" (without pressing the ALT key). I have checked some other applications, and the accelerator actions are only executed when the ALT key is pressed. Is this a .NET problem? How could address this issue? Thanks in

问题 There's a site that I want to continue to hit enter on while I'm away. Is it possible to do something like setInterval(function(){ //have javascript press the button with a certain id },100); I was thinking of just putting that in the smart search bar so it would run the code. 回答1: Well pressing enter is triggering an event .
