In Javascript function onLoadPopulate() is not working?

function onLoadPopulate() {
var grid = $("#grid0");
var numberOfRecords = grid.getGridParam("records");
var dataFromGrid = grid.jqGrid('getGridParam', 'data');
var count=0;
var link;
if(numberOfRecords>0){
numberOfRecords=endNo;
count=begNo-1;
}
for ( ; count < numberOfRecords; count++) {
var program = dataFromGrid[count].program;
var programVal="";
var programs = program.replace(/\s/g,'').split(',');
for ( var i = 0; i< programs.length;i++) {
if (programs[i] == "FS") {
if (programVal == "") {
programVal = 'DOG';
} else {
programVal = programVal.concat(",DOG");
}
} else if (programs[i] == "TF") {
console.log("in TF");
if (programVal == "") {
programVal = 'CAT';
} else {
programVal = programVal.concat(",CAT");
}
}
grid.jqGrid('setCell', count + 1, 'program',
programVal);
}
}
TEST DATA:
program = FS, TF
result i'm getting : DOG but
the result i need : DOG,CAT
When it is doing else if Even if programs[i] = TF it is skipping if loop inside.
Can anyone help with this JavaScript function?
I can't figure it out what is wrong.

issue with input data consisted of special characters i used following replace and it worked
.replace(/[^a-z0-9,\s]/gi,'').replace(/[_\s]/g,'').split(',')

How to underline charachters in InDesign with JavaScript?

I started writing this piece of code for InDesign to underline all letters except from the one with descendants, and added a dialog window to chose stroke and offset of the line.
Now I have two problems:
the program underlines all letters
the stroke and offset won't change
I'm a beginner in Javascript and it's the first time coding for InDesign. Does someone have a clue? Thank you!
// UNDERLINE ALL BUT NO DESCENDANTS
//Make certain that user interaction (display of dialogs, etc.) is turned on.
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.interactWithAll;
if (app.documents.length != 0){
try {
// Run script with single undo if supported
if (parseFloat(app.version) < 6) {
main();
} else {
app.doScript(main, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, "Expand State Abbreviations");
}
// Global error reporting
} catch ( error ) {
alert( error + " (Line " + error.line + " in file " + error.fileName + ")");
}
}else{
alert("Open a document first before running this script.");
}
///MAIN FUNCTION
function main(){
if(app.selection.length != 0){
myDisplayDialog();
}
}
//INTERFACE
function myDisplayDialog(){
//declare variables
//general
var myDoc = app.activeDocument;
var mS = myDoc.selection;
// dialog
var myDialog = app.dialogs.add({name:"Underliner"});
var myLabelWidth = 70;
with(myDialog.dialogColumns.add()){
with(borderPanels.add()){
with(dialogColumns.add()){
with(dialogRows.add()){
staticTexts.add({staticLabel:"Stroke:", minWidth:myLabelWidth});
staticTexts.add({staticLabel:"Offset:", minWidth:myLabelWidth});
}
}
with(dialogRows.add()){
staticTexts.add({staticLabel:""});
var myStroke = measurementEditboxes.add({editValue:1, editUnits:MeasurementUnits.points});
var myOffset = measurementEditboxes.add({editValue: 15, editUnits:MeasurementUnits.points});
}
}
}
var myResult = myDialog.show();
if(myResult == true){
var myStroke = myStroke.editValue;
var myOffset = myOffset.editValue;
myDialog.destroy();
underline(mS,myStroke,myOffset);
}
else{
myDialog.destroy();
alert("Invalid page range.");
}
}
//REAL FUNCTION
function underline(charList,stroke, offset){
var len = charList.length;
const doNotUnderline = ['g','j','p','q','y'];
for (var i=0; i < len; i++){
try{
var myChar = charList[i];
//console.log(typeof myText);
if (includes(myChar, doNotUnderline) == false)
{
myChar.underline = true;
myChar.underlineWeight == stroke;
myChar.underlineOffset == offset;
} else {
myChar.underline = false;
}
}catch(r){
alert(r.description);
break;
}
}
}
//function to know if char is in array
function includes(elemento,array)
{
var len = array.length;
for(var i=0; i<len ;i++)
{
if(array[i]==elemento){return true;}
}
return false;
}

Try these changes in the function underline():
//REAL FUNCTION
function underline(words,stroke, offset) { // <------ here 'words' instead of 'charList'
var charList = words[0].characters; // <------ here get 'characters' of the 'words'
var len = charList.length;
const doNotUnderline = ['g','j','p','q','y'].join(); // <------- here '.join()'
for (var i=0; i < len; i++){
try{
var myChar = charList[i];
// if (includes(myChar, doNotUnderline) == false) // <----- no need
if (doNotUnderline.indexOf(myChar.contents) < 0) // <------ 'indexOf()' instead of 'includes()'
{
myChar.underline = true;
myChar.underlineWeight = stroke; // <------- here '=' instead of '=='
myChar.underlineOffset = offset; // <------- here '=' instead of '=='
} else {
myChar.underline = false;
}
}catch(r){
alert(r.description);
break;
}
}
}
Probably there can be another improvements as well. It's need additional researches. But if you change these lines it should work to a degree.
And there is one little thing that improves user experience greatly: to keep last used values in the input fields. It can be done pretty easy, let me know it you need it.
Update
Here is the way I'm using to store and restore any preferences of my scripts.
Add somewhere at the start of your script these lines:
// get preferences
var PREFS = { stroke: 1, offset: 15 }; // set default prefs
var PREFS_FILE = File(Folder.temp + '/underline_prefs.json'); // the file with preferences
if (PREFS_FILE.exists) PREFS = $.evalFile(PREFS_FILE); // get the prefs from the file
Now you can use the global values PREFS.stroke and PREFS.offset anywhere you want. In your case they go here:
with(dialogRows.add()){
staticTexts.add({staticLabel:""});
var myStroke = measurementEditboxes.add({editValue:PREFS.stroke, editUnits:MeasurementUnits.points});
var myOffset = measurementEditboxes.add({editValue:PREFS.offset, editUnits:MeasurementUnits.points});
}
This way script will get the stroke and weight from the file underline_prefs.json that will be stored in the standard temporary folder of current user.
Final step is to save the values back into the file after the script got them from the dialog window.
I'd put this piece of code here:
if (myResult == true) {
var myStroke = myStroke.editValue;
var myOffset = myOffset.editValue;
myDialog.destroy();
underline(mS, myStroke, myOffset);
// save preferences here
PREFS.stroke = myStroke;
PREFS.offset = myOffset;
PREFS_FILE.open('w');
PREFS_FILE.write(PREFS.toSource());
PREFS_FILE.close();
} else {
myDialog.destroy();
alert("Invalid page range.");
}
Voilá. Now don't need to type the values every time they differ from default ones.

Debugging a push method in Javascript with an object

I am a beginner at js and have a project due by the end of day. I have to display an array with temps added and have set up an object to hold this array. My problem is that the message won't display and the for statement doesn't increment. When passed through both the var i and count come back undefined. I know there is a lot missing from this code but at this point I have tried to stream line it so that I can debug this issue. The date I will deal with later.
Here is my code:
var temps = [];
function process() {
'use strict';
var lowTemp = document.getElementById('lowTemp').value;
var highTemp = document.getElementById('highTemp').value;
var output = document.getElementById('output');
var inputDate = (new Date()).getTime();
var temp = {
inputDate : inputDate,
lowTemp : lowTemp,
highTemp : highTemp
};
var message = '';
if (lowTemp == null) {
alert ('Please enter a Low Temperature!');
window.location.href = "temps.html";
} else if (highTemp == null) {
alert ('Please enter a High Temperature!');
window.location.href = "temps.html";
} else {
lowTemp = parseFloat(lowTemp, 10);
highTemp = parseFloat(highTemp, 10);
}
if (temp.value) {
temps.push(temp.inputDate, temp.lowTemp, temp.highTemp)
var message = '<h2>Temperature</h2><ol>';
for (var i = 0, count = temps.length; i < count; i++) {
message += '<li>' + temps[i] + '</li>'
}
message += '</ol>';
output.innnerHTML = message;
}
return false;
}
function init() {
'use strict';
document.getElementById('theForm').onsubmit = process;
}
window.onload = init;
Here is my new code:
var temps = [];
function process() {
'use strict';
var lowTemp = document.getElementById('lowTemp').value;
var highTemp = document.getElementById('highTemp').value;
var output = document.getElementById('output');
var inputDate = (new Date()).getTime();
var temp = {
inputDate : inputDate,
lowTemp : lowTemp,
highTemp : highTemp
};
var message = '';
if (lowTemp == null) {
alert ('Please enter a Low Temperature!');
window.location.href = "temps.html";
} else if (highTemp == null) {
alert ('Please enter a High Temperature!');
window.location.href = "temps.html";
} else {
lowTemp = parseFloat(lowTemp, 10);
highTemp = parseFloat(highTemp, 10);
}
if (temp.value) {
temps.push(temp.inputDate, temp.lowTemp, temp.highTemp)
var message = '<h2>Temperature</h2><ol>';
for (var i = 0, count = temps.length; i < count; i++) {
message += '<li>' + temps[i] + '</li>'
}
message += '</ol>';
output.innnerHTML = message;
}
return false;
}
function init() {
'use strict';
document.getElementById('theForm').onsubmit = process;
}
window.onload = init;

There are some big issues with your code:
You should never compare anything to NaN directly. The correct comparison should be:
if (isNaN(lowTemp)) {
You're using curly braces when not needed. You should remove both curly braces:
{window.location.href = "temps.html";}
The function parseFloat expects only one parameter: the string to be converted. You're probably confusing it to parseInt which expects both the string and the radix of the conversion.
You're using the temp's property value, but you have never setted it, so, the condition where you check if it exists will always return false, and the push method that you want to debug will never be called, since it's inside that if statement.
Finally, you're closing a li tag at the end, but you have never opened it. You should probably be closing the ol tag you have opened in the begining.
The rest of your code seems pretty OK for me.
Talking about debugging, you should read the Google Chrome's Debugging Javascript Tutorial.

Javascript 'console' infinite loop

I'm experimenting with javascript programs and I hit a snag. The program suddenly lags my browser (infinite loop maybe), dunno why.

bashPrint();
I uploaded it on jsFiddle - http://jsfiddle.net/uQcCP/
Program freezes between:
bashWrite('Error, unknown user. See connect.log for futher information.\n');
and
bashPause(2);
Please, can you help me? Thanks a lot.

The infinite loop starts on line 51: while (window.Bash.queue.length) {
It then ends up in the if statement on line 74, and within this the queue is never shortened:
else if (window.Bash.queue[0]['type'] == 'cursor') {
if (window.Bash.queue[0]['value']) {
window.Bash.span.cursor.style.display = 'inline';
If you find yourself having infinite loop problems in Chrome, open up your development tools and go to the script tab before you open up the page. After you open up the page and it starts looping, you can click the pause button to throw a breakpoint wherever the code is currently executing. From there it's a lot easier to divine where you're getting your error.

First, Firebug is your friend, get used to it. Second, if you paste each function and some supporting lines, one by one, you will eventually get to the following.
var DebugMode = (getQueryVariable("debug")=="1")
function getQueryVariable(variable)
You can't execute getQueryVariable before it is defined, you can create a handle to a future reference though, there is a difference.
There are several other potential issues in your code, but putting the var DebugMode line after the close of the getQueryVariable method should work fine.

It would help if you gave more context. For example, is
Failed to load source for:
http://localhost/js/m.js
the literal text of an error message? Where and when do you see it?
Also, does that code represent the contents of http://localhost/js/m.js? It seems that way, but it's hard to tell.
In any case, the JavaScript that you've shown has quite a few statements that are missing their semicolons. There may be other syntax errors as well. If you can't find them on your own, you might find tools such as jslint to be helpful.

make sure the type attribute in tag is "text/javascript" not "script/javascript".

I know it is more than a year since this question was asked, but I faced this today. I had a
<script type="text/javascript" src="/test/test-script.js"/>
and I was getting the 'Failed to load source for: http://localhost/test/test-script.js' error in Firebug. Even chrome was no loading this script. Then I modified the above line as
<script type="text/javascript" src="/test/test-script.js"></script>
and it started working both in Firefox and chrome. Documenting this here hoping that this will help someone. Btw, I dont know why the later works where as the previous one didn't.
