problems in checking the form input values before submitting using JQUERY
since the form is created dynamically you need to use event delegation $(document).on('submit', '#dimensionAndObjects', function() { alert("haahhhahhaha"); return false; });

Checking For user input between certain limit if not asking again until correct input is entered
You did not allocate memory to hold x and y. Allocate them on the stack and then use the & address of operator to obtain a pointer to that memory. #include <stdio.h> int limitChecker(int x, int y, int input); int main(void) { int x; int y; printf("Enter the width of the windows. (3 - 5) : "); scanf("%d", &x); x = limitChecker(3, 5, x); printf("width: %d ", x); printf("Enter the height of the windows. (2 - 4) : "); scanf("%d", &y); y = limitChecker(2, 4, y); printf("Height: %d ", y); } int limitChecker(int x, int y, int input) { while(!(input>=x && input<=y)) { printf("Please enter a value between (%d - %d): ",x,y); scanf("%d", &input); } return input; } If you want x and y to be poi

Checking input value is an integer
You can check like this: int x; cin >> x; if (cin.fail()) { //Not an int. } Furthermore, you can continue to get input until you get an int via: #include <iostream> int main() { int x; std::cin >> x; while(std::cin.fail()) { std::cout << "Error" << std::endl; std::cin.clear(); std::cin.ignore(256,' '); std::cin >> x; } std::cout << x << std::endl; return 0; }

Checking for invalid input
You're displaying the message for every line that does not contain the ID. What you must do is display it if no line contains the ID. And you'll know that only when you have found the ID (which means that the ID exists), or when you have read all the lines without finding it (which means that the ID doesn't exist) So, you should use a boolean variable idFound initialized to false, and loop until it has become true, or the end of the reader has been met. Then after the loop, you can tell if the ID has been found by examining the value of this boolean variable, and display the message if it's still false. I won't provide code, because you should be able to figure that out by yourself. EDIT: your updated code has two bugs: if (s.split(",")[1].contains(infoToRemove)) { continue; }

Getting the value from input and checking it against a value jquery
First of all, don't use the click button event but the submit event of the form (so it will work when the user press enter) Remember to use return false in the end of the function. To get a value of a input use .val() jQuery(document).ready(function($) { $('#form').submit(function(){ var user = $('input[name="username"]').val(), pwd = $('input[name="password"]').val(); return false; }) });

Python checking for number in input
Use a set. They are iterables, like lists, and can easily be converted back and forth. However, sets do not contain duplicate values. def single_element(): numbers = list(set(input("Enter some numbers: ").split())) print(numbers) In this function, you get the input numbers as a list and convert them to a set, which will remove duplicates, and then convert back to a list. Note: sets are not guaranteed to keep the same order like lists.

Checking whether the user input is a number
You can just use str.isdigit() method: def check(a): if a.isdigit(): print("It's a number!") else: print("It's not a number!") The above approach would fail for negative number input. '-5'.isdigit() gives False. So, an alternative solution is to use try-except: try: val = int(a) print("It's a number!") except ValueError: print("It's not a number!")

Checking if an input is within its range of limits in C++
First off, you don't need all those convolutions with booleans. Just return the expression directly: return (s >= SCHAR_MIN) && (s <= SCHAR_MAX); Second, you should realize that both your functions always yield true: by definition, a signed char is always in the range [SCHAR_MIN, SCHAR_MAX], and an int is always in the range [INT_MIN, INT_MAX]. But if you chose different bounds, this would indeed be the way to do it (taking into account my first remark). As EdS. suggested, you could use a templated solution to reduce the number of functions/overloads you need: template<class T> bool check_range(T value, T min, T max) { return (value >= min) && (value <= max); }

Input checking method in java
The code block below is going to throw a null pointer exception. If the first char is invalid and the first if is executed, then inputline is set to null. Then in the next if you are calling a method on inputline (which is now null) and an exception is thrown. Instead of doing inputline=null;, change it to return null; and just return null right away. if (i<'a' || i>'g') { System.out.println("Invalid input, please enter a letter a to g"); inputLine = null; } int row = i -'a'; if (Character.isDigit(inputLine.charAt(1)))

checking input type button pressed in php
Yes, you can use jQuery/javascript to do this. Generally, you should assign either an ID or a class to your input element to easily identify exactly which control fired the event. Suppose you have this input button: <input type="button" id="mybutt" value="Click Me"> To alert when button is clicked: $(document).ready(function() { $('#mybutt').click(function() { alert('it was pressed'); }); }); The $(document).ready(function() { bit makes sure that the page (DOM) has loaded all elements first, before it allows the code to bind events to them, etc. This is important. NOTE THAT before you use jQuery commands, you must first ensure the jQuery library has been referenced/loaded on your page. Most times we do this in the <head> tags, like so: <head>

Checking content of multiple input fields jQuery
The easiest way is to write a function that uses a basic loop and returns a Boolean value. Get the value of each input field with $('#fieldId'), compare it with your expected answers, and then base the next action on the value returned by the answer-checking function. Based on your example snippet, here's one way to do it: var fields = ['r1c1', 'r1c2', 'r1c3', 'r1c4', 'r1c5'], answers = ['A', 'B', 'C', 'D', 'E']; var checkAnswers = function(fieldArray, answerArray) { for (var i = 0; i < fieldArray.length; i += 1) { if ($('#' + fieldArray[i] + '-input').val() !== answerArray[i]) { // This field doesn't have the correct answer return false; } } // Made it all the way through the loop, so all answers match return true; } if (ch

More pythonic way of checking if user input exists and consists of integers
Since you're checking for integers, and not floats, you can simply do: if self.start.GetValue().strip().isdigit(): pass isdigit() returns False for both cases where the input is an empty string, and when the input contains non-digits. If you want to send specific errors for incorrect assignment: startValue = self.start.GetValue().strip() if not startValue: errors.append("Please provide a start.") if not startValue.isdigit(): errors.append("Value of start must be an integer.")

Convert "m/d/y" date from a form text input field to a mysql datetime "friendly" input?
strtotime() is smart, but it's not psychic or a genius, and when it screws up, it screws up bigtime. Don't use it, especially with ambiguous formats like m/d/y. There's no guarantee it won't be treated as as d/m/y. Use date_create_from_format() instead, which lets you explicitly specify the input format. This is far more reliable, since you'll be in control over how the d and m portions are handled: $ts = date_create_from_format('m/d/Y', '08/06/2013'); $start_date = $ts->format('Y-m-d H:i:s');

C#: Opening form after checking another forms status?

Application.Run(new SplashScreen()); Application.Run(new xMainForm()); Of course, that would not be a real splash screen, which should allow the main window to initialize while the splash is showing, but it would accomplish what you want to do.

How to make something visible in a form by checking a variable?
This is almost how you can do it, the only problem is the Load event will only fire the first time you open a specific instance of a form. Either try to use the Activate event or try something like this: Add a public member to your Mainpage form (might include bugs, haven't written VB.net in several years): Public Sub ToggleTeacher(toggle as Boolean) aboutpage.Visible = toggle End Sub In your other form, you'd then just call this sub rather than modifying Teacher: Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click Me.Close() Enabled11.Show() Mainpage.ToggleTeacher(True); Mainpage.Show() End Sub Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click Me.Close() Mainpage.Tog

Checking form's existence doesn't work
You called Free on the MyForm global method, but you did not modify the reference. So, MyForm still refers to the now destroyed form. And so Assigned(MyForm) evaluates as True, and then the other two tests operate on the stale object reference. Anything could happen when you operate on a stale object reference. In the situations that you have tried, it seems that the operations both return True. But another time you might get an access violation. You'll want to set the MyForm variable to nil after call Free. At the risk of re-starting the great religious Delphi war of our times, you might contemplate using FreeAndNil(MyForm) in place of MyForm.Free. You might find my answer here to be instructive: Why should I not use "if Assigned()" before using or freeing things?

In general, it is not guaranteed to be invoked by HTML user agents. However, there is no word of W3 standard for this. So if you want be 100% sure, you can do somethig like this: $("#login").submit(function (e) { // submit if already checked if($(this).attr("data-checked")) { return true; } $.ajax({
