I'm in a basic flash class where we have to use AS2 and my teacher is out of school for the next week, can anyone help me figure out the syntax errors this code is throwing?
var startX:Number = flashMan_mc._x;
var startY:Number = flashMan_mc._y;
var endX:Number = 450;
var endY:Number = 300;
flashMan_mc.onEnterFrame = function()
{
if (flashMan_mc._x < endX && endY)
{
flashMan_mc._x += ((endX – startX)/30);
}
if (flashMan_mc._y < endX && endY)
{
flashMan_mc._y += ((endY – startY)/30);
}
}
This is throwing these errors:
Scene=Scene 1, layer=actions, frame=1, Line 10 ')' expected
Scene=Scene 1, layer=actions, frame=1, Line 14 ')' expected
Scene=Scene 1, layer=actions, frame=1, Line 15 Unexpected '}' encountered
Check for the '-' signs you have added on line 10 and 15. They are this '–' and not usual '-' signs.
Try deleting those signs and typing again.
var startX:Number = flashMan_mc._x;
var startY:Number = flashMan_mc._y;
var endX:Number = 450;
var endY:Number = 300;
flashMan_mc.onEnterFrame = function()
{
if (flashMan_mc._x < endX && endY)
{
flashMan_mc._x += ((endX - startX)/30);
}
if (flashMan_mc._y < endX && endY)
{
flashMan_mc._y += ((endY - startY)/30);
}
}

Currently using Dart with gsheets_api, which don't seem to have a function to convert column letters to numbers (column index)
As an example , this is what I use with AppScript (input: column letter, output: column index number):
function Column_Nu_to_Letter(column_nu)
{
var temp, letter = '';
while (column_nu > 0)
{
temp = (column_nu - 1) % 26;
letter = String.fromCharCode(temp + 65) + letter;
column_nu = (column_nu - temp - 1) / 26;
}
return letter;
};
This is the code I came up for Dart, it works, but I am sure there is a more elegant or correct way to do it.
String colLetter = 'L'; //Column 'L' as example
int c = "A".codeUnitAt(0);
int end = "Z".codeUnitAt(0);
int counter = 1;
while (c <= end) {
//print(String.fromCharCode(c));
if(colLetter == String.fromCharCode(c)){
print('Conversion $colLetter = $counter');
}
counter++;
c++;
}
// this output L = 12
Do you have any suggestions on how to improve this code?
First we need to agree on the meaning of the letters.
I believe the traditional approach is "A" is 1, "Z" is 26, "AA" is 27, "AZ" is 52, "BA" is 53, etc.
Then I'd probably go with something like these functions for converting:
int lettersToIndex(String letters) {
var result = 0;
for (var i = 0; i < letters.length; i++) {
result = result * 26 + (letters.codeUnitAt(i) & 0x1f);
}
return result;
}
String indexToLetters(int index) {
if (index <= 0) throw RangeError.range(index, 1, null, "index");
const _letters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
if (index < 27) return _letters[index - 1];
var letters = <String>[];
do {
index -= 1;
letters.add(_letters[index.remainder(26)]);
index ~/= 26;
} while (index > 0);
return letters.reversed.join("");
}
The former function doesn't validate that the input only contains letters, but it works correctly for strings containing only letters (and it ignores case as a bonus).
The latter does check that the index is greater than zero.
A simplified version base on Irn's answer
int lettersToIndex(String letters) =>
letters.codeUnits.fold(0, (v, e) => v * 26 + (e & 0x1f));
String indexToLetters(int index) {
var letters = '';
do {
final r = index % 26;
letters = '${String.fromCharCode(64 + r)}$letters';
index = (index - r) ~/ 26;
} while (index > 0);
return letters;
}
I have a converted for-loop in Swift 3.2 that looks similar to this:
for var i in 0..<char.characters.count {
if(self.characters.count > len && ((currentIndex + length2323) < length))
{
i = i - 1
}
}
But, It doesn't work properly. I want to continue loop when set value for i is i = i - 1 but this code getting out of loop
And my previous Swift 2 code is :
for(var i = 0 ; i < char.characters.count ; i += 1) {
if(self.characters.count > len && ((currentIndex + length2323) < length))
{
i = i - 1
}
}
for (index, item) in char.enumerated()
{
//your loop
}
Swift 4 syntax
import UIKit
var char = "char"
var len = 9
var currentIndex = 1
var length2323 = 2323
var length = 17
for var i in 0..<char.count {
if (self.count > len) && ((currentIndex + length2323) < length) {
i = i - 1
}
}
Swift 3.2 syntax
import UIKit
var char = "char"
var len = 9
var currentIndex = 1
var length2323 = 2323
var length = 17
for var i in 0..<char.characters.count {
if (self.characters.count > len) && ((currentIndex + length2323) < length) {
i = i - 1
}
}
After looking at many solutions, I got the following solutions that does exactly what I want.
SOLUTION 1 : works well except it does not work in IE(11)
I will much appreciate if someone can help me out fixing this for IE.
code taken from :https://developer.mozilla.org/en-US/docs/Web/API/HTMLTextAreaElement
function checkRows(oField, oKeyEvent) {
var nKey = (oKeyEvent || /* old IE */ window.event || /* check is not supported! */ { keyCode: 38 }).keyCode,
// put here the maximum number of characters per line:
nCols = 30,
// put here the maximum number of lines:
nRows = 5,
nSelS = oField.selectionStart, nSelE = oField.selectionEnd,
sVal = oField.value, nLen = sVal.length,
nBackward = nSelS >= nCols ? nSelS - nCols : 0,
nDeltaForw = sVal.substring(nBackward, nSelS).search(new RegExp("\\n(?!.{0," + String(nCols - 2) + "}\\n)")) + 1,
nRowStart = nBackward + nDeltaForw,
aReturns = (sVal.substring(0, nSelS) + sVal.substring(nSelE, sVal.length)).match(/\n/g),
nRowEnd = nSelE + nRowStart + nCols - nSelS,
sRow = sVal.substring(nRowStart, nSelS) + sVal.substring(nSelE, nRowEnd > nLen ? nLen : nRowEnd),
bKeepCols = nKey === 13 || nLen + 1 < nCols || /\n/.test(sRow) || ((nRowStart === 0 || nDeltaForw > 0 || nKey > 0) && (sRow.length < nCols || (nKey > 0 && (nLen === nRowEnd || sVal.charAt(nRowEnd) === "\n"))));
return (nKey !== 13 || (aReturns ? aReturns.length + 1 : 1) < nRows) && ((nKey > 32 && nKey < 41) || bKeepCols);
}
<form>
<p>Textarea with fixed number of characters per line:<br />
<textarea cols="50" rows="10" onkeypress="return checkRows(this, event);" onpaste="return false;" /></textarea></p>
</form>
SOLUTION 2
It works in IE but it fails in when editing the lines. You type a line, go back using left arrow keys and type you can type 1 letter and the cursor goes back to the end.

function setCaretPosition(ctrl, pos) {
if (ctrl.setSelectionRange) {
ctrl.focus();
ctrl.setSelectionRange(pos, pos);
}
else if (ctrl.createTextRange) {
var range = ctrl.createTextRange();

Try this one, it may solve this problem.
function ValidationAddress() {
var allText;
allText = document.getElementById("<%= txtAdd1.ClientID %>").value;
allText = document.getElementById('<%=txtAdd1.ClientID%>').value;
var A = allText.split('\n');
var L = A.length;
if (L > 3 && event.keyCode != 8 && event.keyCode != 46) {
alert("You have exceeded maximum limit.Cannot insert more than 3 lines.");
valert = false;
return false;
}
var arr = allText.split("\n");
for (var i = 0; i < arr.length; i++) {
if (arr[i].length > 10) {
alert("You have exceeded the Maximum Limit..Characters per line is 70 in Address Field !");
valert = false;
return false;
}
}
}
I have this piece of code:
(function() {
"use strict";
angular
.module("Default")
.directive(
"numberToTime",
["$rootScope", "$compile", "$log",
function($rootScope, $compile, $log) {
return {
"restrict": "A",
"transclude": true,
"replace": true,
"scope": {
"time": "="
},
"link": function(scope, ele, attrs) {
/**
* Function to add one serie of string to another untill complete
* certain length
*
*/
var _lpad = function(str, padString, length) {
while (str.length < length) {
str = padString + str;
}
return str;
};
/**
* Function to turn a number into time format
*/
var _2time = function(s, hideDays, hideSeconds) {
var d = Math.floor(s / (24 * 60 * 60));
s -= d * (24 * 60 * 60);
var h = Math.floor(s / (60 * 60));
s -= h * (60 * 60);
var m = Math.floor(s / 60);
s -= m * 60;
s = Math.floor(s);
var time = "";
if (!hideDays) {
time += d > 0 ? d + " day" + (d > 1 ? "s" : "") + ", " : "";
}
time += _lpad(h.toString(), '0', 2) + ":" + _lpad(m.toString(), '0', 2) + (hideSeconds ? "" : (":" + _lpad(s.toString(), '0', 2)));
return time;
};
var _setTime = function(time) {
var _time = _2time(time, attrs.hidedays != "false", attrs.hideseconds != "false");
ele.html(_time);
};
scope.$watch("time", function() {
_setTime(scope.time);
}, true);
}
};
}
]
)
;
})();
It works ok, if I have something like:
<span number-to-time time="time"></span>
where
$scope.time = 1234;
It turns that number into readable time format. However, in iOS it does not updates the html.
I have it in a player, and if I log the html() content of ele, it says it has the correct time, but in the page I still see 00:00:00, and the time does not updates correctly. What am I doing wrong?
FIXING
Instead of using .html use .text:
ele.text(_time);
Looks like your page is not being rendered. Instead of using html, use text.
var _setTime = function(time) {
var _time = _2time(time, attrs.hidedays != "false", attrs.hideseconds != "false");
ele.text(_time);
};

This ActionScript code I have been working on for a few days now works 100% just fine in JavaScript, but when I try to compile it in ActionScript it says I have unexpected /, ), and } symbols. Is this syntax wrong and if so how should I fix it? I figured I could test it as Javascript for quicker testing using http://jsfiddle.net/ but now I'm like =(
