I have a translation of a properties file into Pashto and Dari. Does anyone know how I can save this file to read the content as right-to-left?
I know I am able to toggle to read it right to left in Notepad editor, but I need the raw data to be set to right-to-left.
Thanks in advance!
Stephanie
I dont think that JS has a native way of reading files from right to left.
As a workaround, you could try to create a new string that will be the reversed version of the string you just read.
function reverseWord(x) {
return x.split("").reverse().join("")
}
So, when you're preparing the file to be saved and you want to iterate through all of the lines, add the reverseWord function into the loop.
There may be custom libraries that help with this.

I'd like to preface this by saying I'm new to JQuery and this may be a simple question, but I was unable to find a solution after searching to the best of my ability.
I am trying to build a path to an image, where I am working with an API which returns an object that gives part of the path but not the base path.
Ex:
Base path = Youtube.com/watch/?
Path piece from API: /gdsrhab
On line 29 you can see I am trying to perform string concatenation within trying to build the "results" string. I understand why this is not working the way I've set it up, but am not sure how to syntactically perform this (if possible).
I've also tried to create two variables: baseURL and apiURL, concatenate them and save the result into completeURL then substitute it in, but it JQuery takes the string literal "completeURL" instead of substituting the value of the variable. Could someone point me in the right direction for how to get the full path within the tag? Thanks in advance for your help.

In the following picture you can see the second half of the path is missing
The error message I receive
You are using ES6 string templates at start, so you only need to set your variable inside the ${}, you dont need to concate it, the string template will do it for you. So instead of
<img src = 'http...../' + '${movie.poster_path}'}>
that will output something like:
<img src="'http://yoururl.com/'+'mypath'"
you only need to do
<img src = 'http://yoururl.com/${movie.poster_path}'>
inside your string template
I need to dump the data from nseindia to the excel.please find the preview of nseindia in below link. From the webpage i need the OPEN HIGH LOW CLOSE and TotalBuyQty, TotalSellQty values in the excel sheet, can anyone help me on the same. I tried normal webpage dump but it is not working.

Just use Excel to sort.
Thisis what happened when I recorded a sort in Excel.
Range("A1:A18").Sort Key1:=Range("A2"), Order1:=xlAscending, Header:= _
xlYes, OrderCustom:=1, MatchCase:=True, Orientation:=xlTopToBottom, _
DataOption1:=xlSortNormal
Here's a good guide to using the sort function without recording--you can trim it down if you're not using special methods.
sheet("Sheet1").range("Range1").sort key1:=Range("A2"), _
order1:=xlAscending, Header:=xlYes

If you're doing other manipulations to the field after that, you might want to use the AutoFilter as well. Here's a helpful site for that if you're interested:

I'm having a little trouble getting the htmlparser2 module (using node.js) to output an xml string. Basically I'm parsing it in like so:
var htmlparser=require('htmlparser2');
function(xmlString,cb){
var handler=new htmlparser.DomHandler(cb);
var parser = new htmlparser.Parser(handler);
parser.write(xmlString);
parser.done();
}
Then I get an object called "dom", which I do some work on. After that work is done, I want to export it back into an XML string. I know that htmlparser.DomUtils.getOuterHTML(dom) works for HTML objects, but doesn't work for XML (at least not by default). I get back <undefined></undefined> when I call htmlparser.DomUtils.getOuterHTML(dom) on an xml dom.
Thanks in advance for any help you're able to offer!

Fixed. Basically you need to use a second option in getOuterHTML...
htmlparser.DomUtils.getOuterHTML(dom,{xmlMode:true})
If that doesn't work, try calling on the inner elems in the array like:
htmlparser.DomUtils.getOuterHTML(dom[0],{xmlMode:true})
You'll have to wrap a for loop around it to get the whole document, but it works for me!
There is some data that I need to get from a local crawled page. It's inline javascript like this:
<script type="text/javascript">
//<![CDATA[
var graph_data = {"query":{"cid":["13908"],"timestamp_from":1402531200,"timestamp_till":1402531200,"views":1138942,"data":
etc, the variable is very long but you get the idea. I want to put "graph_data" into an array called $data. What is the best way to do this? I should add this is all being done by me locally & I don't need to execute any javascript code, just extract the data.
I have make a suggestion purely as an idea with some code worth trying!
As suggested, the DOM Document may provide this much easier, but here's another possible solution for extracting...
I'm guessing that the var graph_data is a JSON string that you want to extract from the HTML page so that you can store as a PHP var. The problem is that your code doesn't show how the variable ends but I'm going to assume that a new line break would be the way to identify the end of the variable being set. It may be a semi-colon though and if it is, instead of "\r\n" try ";"
// Assuming your html code is stored in $html...
preg_match("/var graph_data[^\{]*?(\{[^\r\n]+?)/is",$html,$match);
print "<pre>";
print_r($match);
print "</pre>";
This should result in $match[1] storing the part you need.
You can try passing that into json_decode() but that's touching some wood with crossed fingers.
Good luck...
I am using less.js (1.3.0) to parse less to css on the client side. Inside the parsers' callback I want to get the value for each variable. i tried the following without success.
var data = "#colour: red; #example { background-color: #colour; }",
parser = new less.Parser({});
parser.parse(data, function (error, root) {
console.log( root.toCSS() );
var varsDef = root.variables();
for (k in varsDef) {
console.log(varsDef[k]);
// how to get the value for the var?
//not working
console.log(varsDef[k].eval());
//not working
console.log(varsDef[k].toCSS());
//is an object but looking for a string value
console.log(varsDef[k].value);
//returns an empty string
console.log(varsDef[k].value.toCSS());
}
});
Neither eval() nor the toCSS() gave me any results. I do not understand the less parsers' inner workings. Each variable object has a variable property varsDef[k].value which is an object itself. But I just need the string value of the variable.
Does anyone know how to get the variables' values as a string?
varsDef[k].value.toCSS()
should be the value
varsDef[k].name
should be the variable name
varsDef[k].toCSS()
returns nothing because it is a variable - in CSS variables do not output.
i ran into this problem recently and it bit me because, like you, i had the same instinct of running something like very much like the code you wrote above but for complex variables along the lines of
#redColor: #900; // responds to .toCSS()
#fooColor: desaturate(#redColor, 20%); // both of these error out
#barColor: lighten(#fooColor, 10%); // when calling .toCSS()
you'd get this nested tree.Value for #barColor which was this nested representation of the parse tree, so it would say, unhelpfully that barcolor: {[value: {value: [{lighten: {...}}]}]} or somesuch. my parsing-fu is pretty bad because i would always end up with some object at some point which would no longer respond to me invoking tree.toCSS on it, so i gave up on that route.
Instead, what i did was generated a nonsense .less file with an import rule and a nonsense rule, like so
#import "varfile.less";
.foo {
redColor: #redColor;
fooColor: #fooColor;
barColor: #barColor;
}
less will happily parse such a file, it doesn't care if redColor is a real css property or not, it just ignores it and does all the substitutions where it has to dutifully. And so you actually end up with a single rule css file that you can easily parse since it's very straightforwardly marked up. it looks like this:
.foo{
redColor: #990000;
fooColor: #8a0f0f;
barColor: #b81414;
}
this is, coincidentally, the easiest file to parse. it practically begs to be turned into json or what have you. granted, the path to here is pretty comical. i suspect it's because a variable without a rule is still fair game to be modified within the rule itself, but i could just be rationalizing that.
assuming you only want to extract the final values of your less vars and not the semantic values of your less vars, it's pretty handy. if you want semantics, it seems better to just parse the actual less file.
i ended up writing this in node and after i got past my own objections to how dodgy it felt, it worked quite well and fed me a json dict with my project's variables. you can take a look, it's on github at nsfmc/less-extractor which basically takes a basic config file and then writes to stdout a json dict. it's inelegant, but it totally works, even if it's a bit hackish.
your original question asked about doing this entirely client-side, so that would appear to rule out that github project, but the idea is very similar: you want to be able to access the original less file as part of some xhr request, parse it to get the variable names, build a less string, parse that, and then the rest of the code is just string building and run of the mill parsing.
hope that helps you!
I was also having issues with the less parser too; doing it that way was getting ridiculous with recursive checking of tree nodes.
If you wan't the actual values as opposed to the CSS generated (as per the above answer), the best way is to probably manually parse the file's text.
This function returns a key/value pair for each of the variables in a given less file. It wont work if the LESS file has multiple values per line, you could make it better with regex. I used it to parse bootstrap's variables file, which works nicely.
getLessVars = (lessStr) ->
lines = lessStr.split('\n')
lessVars = {}
for line in lines
if line.indexOf('#') is 0
keyVar = line.split(';')[0].split(':')
lessVars[keyVar[0]] = keyVar[1].trim()
return lessVars
