I have an array that comes in from from my API that I would like to arrange in a way that is better for the user (namely, in a column as opposed to the typical comma separated printed array).
This is my JS Fiddle to give a clearer picture: https://jsfiddle.net/2z89owas/
My question is, how can I get output3 to display just like output (and maintain its status as an iterable array like it was as dates)?
First you should not be using value for an html element. You can use .value for extracting value from inputs. Change your line to:
var val = document.getElementById('output2').innerHTML;
Afterwards, you have to split the same way you did join.
var dates3 = val.split('<br>');
document.getElementById('output3').innerHTML = dates3;
You can directly use join, something like:
document.getElementById('output3').innerHTML = dates.join(',');
You can try mapping over the contents of dates instead, as so:
let datesElem = dates.map(date =>`<p>${date}</p>`);
// test: console.log(datesElem)
document.getElementById('output3').innerHTML = datesElem

Okay, so I have a filepath with a variable prefix...
C:\Users\susan ivey\Documents\VKS Projects\secc-electron\src\views\main.jade
... now this path will be different for whatever computer I'm working on...
is there a way to traverse the string up to say 'secc-electron\', and drop it and everything before it while preserving the rest of it? I'm familiar with converting strings to arrays to manipulate elements contained within delimiters, but this is a problem that I have yet to come up with an answer to... would there be some sort of regex solution instead? I'm not that great with regex so I wouldn't know where to begin...
What you probably want is to do a split (with regex or not):
Here's an example:
var paragraph = 'C:\\Users\\susan ivey\\Documents\\VKS Projects\\secc-electron\\src\\views\\main.jade';
var splittedString = paragraph.split("secc-electron"); // returns an array of 2 element containing "C:\\Users\\susan ivey\\Documents\\VKS Projects\\" as the first element and "\\src\\views\\main.jade" as the 2nd element
console.log(splittedString[1]);
You can have a look at this https://www.w3schools.com/jsref/jsref_split.asp to learn more about this function.
With Regex you can do:
var myPath = 'C:\Users\susan ivey\Documents\VKS Projects\secc-electron\src\views\main.jade'
var relativePath = myPath.replace(/.*(?=secc-electron)/, '');
The Regex is:
.*(?=secc-electron)
It matches any characters up to 'secc-electron'. When calling replace it will return the last part of the path.
You can split the string at a certain point, then return the second part of the resulting array:
var string = "C:\Users\susan ivey\Documents\VKS Projects\secc-electron\src\views\main.jade"
console.log('string is: ', string)
var newArray = string.split("secc-electron")
console.log('newArray is: ', newArray)
console.log('newArray[1] is: ', newArray[1])
Alternatively you could use path.parse(path); https://nodejs.org/api/path.html#path_path_parse_path and retrieve the parts that you are interested in from the object that gets returned.
So lets say I have a mailto email in which a checkbox question exists that asks the user to pick the best fruits out of a list of fruits (check all that apply.) They end up with apples, bananas, and pears. The mailto email that they trigger then contains the following (assuming the checkboxes in the question are named bestFruits):
...
bestFruits=apples
bestFruits=bananas
bestFruits=pears
...
So in my javascript file, I have the following line to parse values from the email:
var bestFruits = mail.bodyText.match(/bestFruits=\s*(\S.*\S)\s*/);
So my issue is that this would (presumably) take only one value by the end. What I need, is for the javascript to loop and add each value of bestFruits in the email to the bestFruits var so that each value (apples, bananas, and pears) are all in the bestFruits var.
Is there any way to do this? I tried making a for loop, but I couldn't determine the syntax to loop through the mailto email body and add each instance of bestFruits to the variable.
I'm still extremely new to all this, as I was thrust in recently. If I'm missing something fundamental, I'd appreciate a quick pointing-out. If you require any more info, I'd be happy to try to provide it.
Thanks for reading guys!
You don't need looping. You do need to match all the fruits (as per your example, matching all single words after bestFruits), remove bestFruits= from the matches, join the resulting array and store it in a variable. Like this:
var bestFruits = mail.bodyText.match(/bestFruits=\w+/g)
.map(function(x){return x.split('=')[1]})
.join(',');
What does it do:
Matches all your best fruits.
Takes each bestFruits=abc element and replaces it with abc (i.e., splits with = separator and takes the second part)
Makes the string of your fruits (converts the resulting array to string with , joiner).
You were very close - modified your regex a little bit:
var body = `this=is
an=example
bestFruits=apples
bestFruits=bananas
bestFruits=pears
of=doing
things=ok?
`;
var re = /bestFruits=(.*)/g;
var fruitMatches = body.match(re);
var bestFruits = fruitMatches.map(function(fruitMatch) {
return fruitMatch.split('=')[1];
});
console.log(bestFruits); // ["apples", "bananas", "pears"]

I am trying to fetch numeric value from link like this.
Example link
/produkt/114664/bergans-of-norway-airojohka-jakke-herre
So I need to fetch 114664.
I have used following jquery code
jQuery(document).ready(function($) {
var outputv = $('.-thumbnail a').map(function() {
return this.href.replace(/[^\d]/g, '');
}).get();
console.log( outputv );
});
https://jsfiddle.net/a2qL5oyp/1/
The issue I am facing is that in some cases I have urls like this
/produkt/114664/bergans-of-norway-3airojohka-3jakke-herre
Here I have "3" inside text string, so in my code I am actually getting the output as "11466433" But I only need 114664
So is there any possibility i can get numeric values only after /produkt/ ?
If you know that the path structure of your link will always be like in your question, it's safe to do this:
var path = '/produkt/114664/bergans-of-norway-airojohka-jakke-herre';
var id = path.split('/')[2];
This splits the string up by '/' into an array, where you can easily reference your desired value from there.
If you want the numerical part after /produkt/ (without limitiation where that might be...) use a regular expression, match against the string:
var str = '/produkt/114664/bergans-of-norway-3airojohka-3jakke-herre';
alert(str.match(/\/produkt\/(\d+)/)[1])
(Note: In the real code you need to make sure .match() returned a valid array before accessing [1])
I have an array like this:
var people = [
'<option value=\'64\'>Tom',
'<option value=\'76\'>Dan',
];
I am looping through each item in the array to extract the value (like the number 64 in the first item) and the text (like Tom in the first item). I tried multiple ways of extracting these details from each item but I am unable to. I even tried using substrings and other methods. Can someone tell me how to extract this information?
You should use a regular expression in such a case.
For example:
var things = people.map(function(s){
return s.match(/(\d+)\W+(\w+)$/).slice(1)
});
This builds this array:
[ ["64", "Tom"], ["76", "Dan"] ]
You might want to adapt it for your precise needs:
check an array is returned by match, if some strings might be invalid
change the regex if the pattern is more variable
Note that you probably shouldn't have such an array to start with. If you generate it server-side, you should opt for the generation of a JSON structure instead and let the client script build the interface from the data, instead of building it from something which is neither clean data nor GUI.
You can use multiple split :
var str = '<option value=\'64\'>Tom';
var tmpStr = str.split("'");
var number = (tmpStr[1].split("\\"))[0];
var name = (tmpStr[2].split(">"))[1];
document.write(number + " " + name);
Lets say I have this input:
name="fecha_inicio[2]"
And I want to clone it and generate:
name="fecha_inicio[3]"
How can I do so?
I tried something like this, but Its ugly and it won't work..
var $input = $original.clone();
var name = $input.attr('name');
name.replace('['+(indice-1)+']', '['+indice+']');
$input.attr('name', name);
replace method doesn't modify string in place, but returns a new string. So your code should be:
name = name.replace('['+(indice-1)+']', '['+indice+']');
Also maybe you don't really need to have such index names. You can simply go with name="fecha_inicio[]" and don't worry about index. Later you would get form data with say serialize method.
