I have the following code in javascript:
var c = new addon.Component();
c.ComponentLength = 3
How should i build my addon, so i can do the previous code? I've already followed the tutorials in http://nodejs.org/api/addons.html , but i'm stuck here.
Is this possible? Does anyone have a solution?
Thanks in advance.
The solution is on the v8.h, search for SetAccessor , which "Sets an accessor on the object template.".

I'm working on this WP plugin and I've been trying to get the ID of a custom post kinda thing that is declared in the body class on each page. So it goes like this;
<body class="(Bunch of other classes) ld-courses-1731-parent">
I'm trying to get the number 1731 in my JS function but the number is dynamic so I need to some regex matching with the string pattern.
Pattern: ld-courses-*INT VALUE*-parent
how can I do this with JS? Any help is much appreciated thank you so much.
You can use match if thats the only class in your body:
var classList = document.getElementsByTagName("body")[0].classList;
[...classList].forEach(function(thisClass) {
if (/ld-courses-\b/.test(thisClass)) {
var id = thisClass.match(/\d/g);
console.log(id.join(""));
}
});
<body class="another-class-before another-class-12-hasnum ld-courses-1731-parent another-class-12-hasnumaswell another-class-after">
</body>
Hi Laclogan in regards to your question yes it's possible for sure.
Correct me if i'm wrong but the number comes probably if it's changing for each post directly from the url.
The following site explains if this is the case how to get that number from the url.
https://www.sitepoint.com/get-url-parameters-with-javascript/
In addition you can use the function concat to combine the strings see this site for an example hope it helps.
https://www.w3schools.com/jsref/jsref_concat_string.asp
Could you confirm for me that the number is always present in the url or if this is not the case?
How can I add a route to a UI5 geomap using js? I didn't find anything in the samples or the documentation.
Has it something to do with the method addGeoJsonLayer()?
Thanks in advance for your help :)
I found a way to do it. You have to create a VO Object as it is outlined here: https://sapui5.hana.ondemand.com/test-resources/sap/ui/vbm/bestpractices.html
then add it using addVo()
like it is outlined here https://sapui5.hana.ondemand.com/docs/api/symbols/sap.ui.vbm.GeoMap.html#addVo
Example:
var oRouteCollection = new sap.ui.vbm.Routes
next
oGeoMap.addVo(oRouteCollection);

Please advise on how to push to GTM dataLayer the value below step by step (I'm not a developer).
document.getElementById("mytdId").innerText
Thanks a lot.
ok i found a way around which works , here the snippet :
Hi
function (){
var topMenu = document.getElementById("dm1m0i1tdT").innerText;
return(topMenu);
}
To improve the syntax you suggest an array but don't know how to handle that in this case here. Any suggestion ?
I am trying to retrieve random 200 objects from the array returned to me by query.find() method. First i tried to implement all random number generation and all . And just now i got introduced to underscore.js method "_.sample" .
But something is going wrong. I dont have much knowledge of underscore.js. So if someone could help that will be great.
When i try to sun _.sample method it give me the error :
TypeError: Object function (e){if(e instanceof T)return e;if(!(this instanceof T))return new T(e);this._wrapped=e} has no method 'sample'
Someone please explain what exactly this error is. I tried searching but didn't get explanatory content. Thank you in advance.
Here's the code :
var queryPhrases = new Parse.Query("Phrases");
queryPhrases.select("phraseId");
queryPhrases.find().then(function(phrases){
var arrayOfUnused = _.sample(phrases,request.params.count);
user.add("usedPhrases",arrayOfUnused);
user.save();
response.success(arrayOfUnused) ;
});
Parse Cloud Code includes an outdated version of Underscore, but frustratingly, I can't find anything stating which version. While Underscore no longer ships with the Parse Javascript SDK as of v1.6.0 (late 2015), previously it had only used UnderscoreJS v1.4.4 (early 2013), so I'd expect Cloud Code to be using something from around then.
Adding the latest Underscore source to your Cloud Code is always an option, and then require it like any other of your own files.
Alternatively, I used the following to show a list of functions available in the included Underscore Cloud Code module.
var _ = require('underscore');
var availableFunctions = _.functions(_);
console.log('Available Underscore Functions: ' + JSON.stringify(availableFunctions));
Thanks a lot guys for your responses. I couldn't find the reason or the solution to run _.sample in my code. So i implemented it the other way. Here's what i did.
var arrayOfUnused = _.first(_.shuffle(phrases),request.params.count);
This works. :-)
I was trying to export https://github.com/LiosK/UUID.js into a module, but I'm having a rough time - version 4 is worthless to me (use case Cassandra) - does anybody know of a binding for these types of uuids? I can't seem to find one on Google...maybe someone has implemented what's out there?
Thanks!
I think you can just use /dist/uuid.core.js with a slight modification as follows:
add the following line and save:
exports.UUID = UUID;
now in another file use:
var UUID = require("path/to/the/uuid.core.js");
console.log(UUID.generate());
hope that helps

https://github.com/broofa/node-uuid now supports v1 format IDs. FWIW.
