I am using a report parameter in BIRT.
It a string, which contains the month/year, like: 08/2018
To test the value, I am using the following code. It is located in a Dynamic Text:
var dateStringArray = params["monthYear"].value.split("/");
var date = new Date(parseInt(dateStringArray[1]), parseInt(dateStringArray[0]) - 1, 1);
var t = parseInt(dateStringArray[0]);
t;
If I fill the parameter with 08/2018, I get a NaN, see:
But if I fill the parameter with 07/2018, it is working correctly:
I have tested it with several numbers. It is just not working with 08 and 09. All other number til 10 are working...
This seems to be a weird scenario. Need to raise a bug on this.
But for your workaround, you can make use of the code below in Dynamic Text which is working fine:
var dateStringArray = params["monthYear"].value.split("/");
var monNum;
if (BirtStr.charLength(dateStringArray[0]) == 2)
{monNum = BirtStr.right(dateStringArray[0],1);}
else {monNum = dateStringArray[0];}
monNum;
//var date = new Date(parseInt(dateStringArray[1]), parseInt(dateStringArray[0]) - 1, 1);
var t = parseInt(monNum);
t;

Having some trouble getting this right. I'm very new to jQuery, so trying to get better and learn.
Currently I am getting 2 different values from a html table using the following code
var sellPrice = $('.qt').find("tr:eq(2)").find("td:eq(4)").html();
var buyPrice = $('.break .main-col .qt').find("tr:eq(2)").find("td:eq(4)").html();
These both output a value such as $13,000,000
I am then wanting to subtract 1 from these values (making it $12,999,999) before pasting them to an input as such
$('input[name="sell"]').val(sellPrice);
$('input[name="buy"]').val(buyPrice);
However, I am having some trouble with how to subtract $1 from these.
I tried using sellPrice--; but without success.
I've also tried adding - 1; at the end of each variable, but did not succeed either.
I tried to test something like this, but did not work either.
var minusOne = -1;
var getCurrentSellPrice = $('.qt').find("tr:eq(2)").find("td:eq(4)").html();
var getCurrentBuyPrice = $('.break .main-col .qt').find("tr:eq(2)").find("td:eq(4)").html();
var sellPrice = (getCurrentSellPrice - minusOne);
var buyPrice = (getCurrentBuyPrice - minusOne);
$('input[name="sell"]').val(sellPrice);
$('input[name="buy"]').val(buyPrice);`
Trying my best to familiarize myself with jQuery :)
Any help is much appreciated!
Solved using this
var getCurrentSellPrice = $('.qt').find("tr:eq(2)").find("td:eq(4)").html();
var getCurrentBuyPrice = $('.break .main-col .qt').find("tr:eq(2)").find("td:eq(4)").html();
var sellPrice = Number(getCurrentSellPrice.replace(/[^0-9\.]+/g,"")) - 1;
var buyPrice = Number(getCurrentBuyPrice.replace(/[^0-9\.]+/g,"")) + 1;
$('input[name="sell"]').val(sellPrice);
$('input[name="buy"]').val(buyPrice);
Since your numbers contain currency symbol and are strings, you need to convert them to proper numbers before subtracting them. See the answer below.
How to convert a currency string to a double with jQuery or Javascript?
I am developing a simple application form where I am calculating experiences from maximum three employers. Now I want to add them up . The experiences are in the form of X years Y months and Z days. I have written following javascript function --
function total(){
var td;
var fd=parseInt(document.getElementById("LoS_days1").value);
var sd=parseInt(document.getElementById("LoS_days2").value);
var ld=parseInt(document.getElementById("LoS_days3").value);
var tm;
var fm=parseInt(document.getElementById("LoS_months1").value);
var sm=parseInt(document.getElementById("LoS_months2").value);
var lm=parseInt(document.getElementById("LoS_months3").value);
var ty;
var fy=parseInt(document.getElementById("LoS_year1").value);
var sy=parseInt(document.getElementById("LoS_year2").value);
var ly=parseInt(document.getElementById("LoS_year3").value);
td = (fd +sd +ld);
var rd = td%30;
var cm = Math.floor(td/30);
document.getElementById("Totalexp_day").value=rd;
tm = (cm + fm +sm +lm);
var rm = tm%12;
var cy = Math.floor(ty/12);
document.getElementById("Totalexp_month").value=rm;
ty = (cy + fy +sy +ly);
document.getElementById("Totalexp_year").value=ty;
}
I am getting a NaN message in each of the Totalexp_day, Totalexp_month and Totalexp_day field. Earlier I had some modified code that was not showing NaN message but it was not showing the desired results. Kindly suggest what to do to eliminate these two errors.
parseInt(document.getElementById("LoS_days1").value)
if the first character of the string cannot be converted to a number, parseInt will return NaN.
To avoid this, you can so something like is suggested here:
parseInt(document.getElementById("LoS_days1").value) || 0
If document.getElementById("Totalexp_day").value is empty then also it will return NaN. Make sure you have some number there.
Second alternative is reading document.getElementById("Totalexp_day").innerHTML and then applying parseInt
Probably you alert or console log the document.getElementById("Totalexp_day").value you would be more clearer why this problem is comming
If I do:
var number = 3500;
alert(number.toLocaleString("hi-IN"));
I will get ३,५०० in Hindi.
But how can I convert it back to 3500.
I want something like:
var str='३,५००';
alert(str.toLocaleNumber("en-US"));
So, that it can give 3500.
Is it possible by javascript or jquery?
I think you are looking for something like:
https://github.com/jquery/globalize
Above link will take you to git project page. This is a js library contributed by Microsoft.
You should give it one try and try to use formt method of that plugin. If you want to study this plugin, here is the link for the same:
http://weblogs.asp.net/scottgu/jquery-globalization-plugin-from-microsoft
I hope this is what you are looking for and will resolve your problem soon. If it doesn't work, let me know.
Recently I've been struggling with the same problem of converting stringified number formatted in any locale back to the number.
I've got inspired by the solution implemented in NG Prime InputNumber component. They use Intl.NumberFormat.prototype.format() (which I recommend) to format the value to locale string, and then create set of RegExp expressions based on simple samples so they can cut off particular expressions from formatted string.
This solution can be simplified with using Intl.Numberformat.prototype.formatToParts(). This method returns information about grouping/decimal/currency and all the other separators used to format your value in particular locale, so you can easily clear them out of previously formatted string. It seems to be the easiest solution, that will cover all cases, but you must know in what locale the value has been previously formatted.
Why Ng Prime didn't go this way? I think its because Intl.Numberformat.prototype.formatToParts() does not support IE11, or perhaps there is something else I didn't notice.
A complete code example using this solution can be found here.
Unfortunately you will have to tackle the localisation manually. Inspired by this answer , I created a function that will manually replace the Hindi numbers:
function parseHindi(str) {
return Number(str.replace(/[०१२३४५६७८९]/g, function (d) {
return d.charCodeAt(0) - 2406;
}).replace(/[०१२३४५६७८९]/g, function (d) {
return d.charCodeAt(0) - 2415;
}));
}
alert(parseHindi("३५००"));
Fiddle here: http://jsfiddle.net/yyxgxav4/
You can try this out
function ConvertDigits(input, source, target) {
var systems = {
arabic: 48, english: 48, tamil: 3046, kannada: 3302, telugu: 3174, hindi: 2406,
malayalam: 3430, oriya: 2918, gurmukhi: 2662, nagari: 2534, gujarati: 2790,
},
output = [], offset = 0, zero = 0, nine = 0, char = 0;
source = source.toLowerCase();
target = target.toLowerCase();
if (!(source in systems && target in systems) || input == null || typeof input == "undefined" || typeof input == "object") {
return input;
}
input = input.toString();
offset = systems[target] - systems[source];
zero = systems[source];
nine = systems[source] + 9;
for (var i = 0 ; i < input.length; i++) {
var char = input.charCodeAt(i);
if (char >= zero && char <= nine) {
output.push(String.fromCharCode(char + offset));
} else {
output.push(input[i]);
}
}
return output.join("");
}
var res = ConvertDigits('१२३४५६७८९', 'hindi', 'english');

then
var cldr = require("cldr-data");
var Globalize = require("globalize");
Globalize.load(cldr("supplemental/likelySubtags"));
Globalize.load(cldr("supplemental/numberingSystems"));
Globalize.load(cldr("supplemental/currencyData"));
//replace 'hi' with appropriate language tag
Globalize.load(cldr("main/hi/numbers"));
Globalize.load(cldr("main/hi/currencies"));
//You may replace the above locale-specific loads with the following line,

A common scenario for this problem is to display a float number to the user and then want it back as a numerical value.
In that case, javascript has the number in the first place and looses it when formatting it for display. A simple workaround for the parsing is to store the real float value along with the formatted value:
var number = 3500;
div.innerHTML = number.toLocaleString("hi-IN");
div.dataset.value = number;
Then get it back by parsing the data attribute:
var number = parseFloat(div.dataset.value);
This is a Columbus's egg style answer. It works provided the problem is an egg.
var number = 3500;
var toLocaleString = number.toLocaleString("hi-IN")
var formatted = toLocaleString.replace(',','')
var converted = parseInt(formatted)
I would like to find difference between two fields using JavaScript in iText.
I am able to find the sum of them using below code:
PdfStamper stamperResult = new PdfStamper(readersectionResult, new FileOutputStream(RESULT_NEW));
stamperResult .addJavaScript("var nameField = this.getField(\"total\");"+ "nameField.setAction(\"Calculate\",'AFSimple_Calculate(\"SUM\",\"total1\", \"total2\")')");
Is there any way to find the difference using 'AFSimple_Calculate' similar to what I did in the above code snippet?
Thanks for editing! I tried your suggestion but it does not seem to work for some reason.
stamperResult.addJavaScript(" var total1 = this.getField(\"value1\"); var total2 = this.getField (\"value2\"); var subtr = this.getField(\"total\"); subtr.value = total1.value - total2.value;");
I separated newlines by spaces and added right escape characters.
I was also thinking of using a different logic for subtraction using AF methods : like this
stamperResult.addJavaScript("var nameField = this.getField(\"total\");"+ "nameField.setAction(\"Calculate\",'AFSimple_Calculate(\"SUM\",\"total1\", \"-total2\")')");
In the above code I was trying to add -(negative value) to total 2 so that it will be subtracted from total1 though the AF method is still 'SUM'.
But that does not work.
The below simple code seem to work :
stamperResult.addJavaScript("var nameField = this.getField('total');" +
"nameField.setAction('Calculate'," +
"'subtract()');" +
"" +"function subtract(){this.getField('total').value
= (this.getField('total_1').value -this.getField('total_2').value); }");
I updated your question because it contained many spelling errors. I didn't edit the code snippet because I don't know what the original code snippet is like. In any case: I think something went wrong during the copy/paste process, as I don't think your code snippet compiles in its current state.
In any case: as far as I know the AF-methods (the AF stands for Adobe Forms) may not be present in every viewer, and as far as I know Adobe didn't implement a way to subtract values from each other in the AFSimple_Calculate method.
For these two reasons, you may prefer regular JavaScript instead of using a pre-canned function that may or may not be pre-canned.
This regular JavaScript may look like this:
var total1 = this.getField("total1");
var total2 = this.getField("total2");
var subtr = this.getField("difference");
subtr.value = total1.value - total2.value;
I'm not sure if that answers your question. Maybe you just want:
var total1 = this.getField("total1");
var total2 = this.getField("total2");
var namefield = total1.value - total2.value;
You can put these lines inside a String using the right escape characters and replacing the newlines by spaces or newline characters.
Of course, you need to trigger this code somewhere. Below you'll find an example that puts the negative value of the content of a value1 field into a value2 field.
public static void main(String[] args) throws IOException, DocumentException {
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("js.pdf"));
document.open();
writer.addJavaScript("function makeNegative() { this.getField('value2').value = -(this.getField('value1').value); } ");
Rectangle rect1 = new Rectangle(40, 740, 200, 756);
TextField value = new TextField(writer, rect1, "value1");
value.setBorderColor(GrayColor.GRAYBLACK);
value.setBorderWidth(0.5f);
PdfFormField field = value.getTextField();
field.setAdditionalActions(PdfName.BL, PdfAction.javaScript("makeNegative();", writer));
writer.addAnnotation(field);
Rectangle rect2 = new Rectangle(40, 710, 200, 726);
TextField neg = new TextField(writer, rect2, "value2");
neg.setBorderColor(GrayColor.GRAYBLACK);
neg.setBorderWidth(0.5f);
writer.addAnnotation(neg.getTextField());
document.close();
}
Note that I used a Blur action. This means the method will be triggered as soon as you select another field after filling out the value1 field.
Some days ago, I have found a useful link in which a day on a given date is displayed. I found it very useful for embedding it into some specific applications. It works fine but on some dates, it does not work. Some of dates on which this formula does not work are as follows.
(dd/mm/yyyy)
1/3/1901
2/3/1901
3/3/1901
1/3/1902
2/3/1902
and so on...
The link where this formula was implemented in Javascript is as follows. Just follow it and try the above dates in three textfields given. It will display "undefined" means that it may not be specific to obtain the day on such dates. What should actually be the reason, any idea?
The relevant javascript code is:
var monthCodes = Array(5,1,1,4,6,2,4,0,3,5,1,3);
var weekdays = Array('Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday');
function compute() {
d = conversion.day.value;
m = conversion.month.value;
y = conversion.year.value%100;
c = Math.floor(conversion.year.value/100);
if((conversion.year.value%4==0) && (conversion.year.value%100!=0 || conversion.year.value%400==0) && (m==1 || m==2))
isLeapJanFeb = 1;
else
isLeapJanFeb = 0;
weekday = (1*d + 1*monthCodes[m-1] + 1*y + 1*Math.floor(y/4) - 2*(c%4) - 1*isLeapJanFeb) % 7;
alert(weekdays[weekday]);
}
Note that it works fine in Internet explorer. In some browsers like Mozilla Firefox, it may not work.
Here is the link...

Well yes you found a bug in the JavaScript.
I did a view source and copied it to a fiddle, but JSFiddle appears to be down now. Here is the code:
var monthCodes = Array(5,1,1,4,6,2,4,0,3,5,1,3);
var weekdays =['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'];
var d = +prompt("Day");
var m = +prompt("Month");
var year = +prompt("Year");
var y = year%100;
var c = Math.floor(year/100);
if ((year%4==0) && (year%100!=0 || year%400==0) && (m==1 || m==2))
isLeapJanFeb = 1;
else
isLeapJanFeb = 0;
weekday = Math.floor(1*d + 1*monthCodes[m-1] + 1*y + 1*Math.floor(y/4) - 2*(c%4) - 1*isLeapJanFeb) % 7;
alert("Weekday code computed to be " + weekday);
alert("The weekday is " + weekdays[weekday]);
If you use today's date it will work, but try 1 2 1901.
The problem is that the computation gives -3, and -3 % 7 is -3 and when you index an array with -3 you get undefined.
Maybe some browsers interpret a negative array index as something other than undefined. Perhaps their JS engine works like Ruby and for weekdays[-3] they count from the right end, because after all February 1, 1901 was indeed a Friday!
Again, someone posted some bad code on the internet! Obligatory xkcd reference!
