I am trying to create a function to search for regex in a cell and return a given value if the result is found.
The function works per cell, but I can't get it to work by array applying the function to B1:B10 rather than just B10. I want it to work as array to speed up the function.
I am receiving this error message when I apply pagetype function to an array.
TypeError: Cannot find function search in object yfhhh. (line 13).
I understand that I need to edit the function somehow to have it working on a range of cells but am not sure how...this is my code:
function pageType(string) {
if (string.map) // Test whether input is an array.
return string.map(page); // Recurse over array if so.
else {
return page(string);
}
}
function page(url) {
var productpage = /.*\.html.*/
var homepage = /^http:\/\/www\.domain.com\/$/
var categorypage = /^http:\/\/www\.domain\.com\/.*/
if (url.search(categorypage) > -1)
return "Category Page";
if (url.search(productpage) > -1)
return "Product Page";
if (url.search(homepage) > -1)
return "Homepage";
else
return "Brand Page";
}
There is no search() method for an array. An array is a sub category of the broader category of object. Then there is a JSON object, which is an object.
object - includes
JSON object {'key':'value'}
Array ['element1','element2']
An array is a sub category of an object. It's kind of confusing to call an array an object. But that is what the error message is doing.
Because you are using RegEx, you can't use indexOf(), which is a method of both a string and an array.
You could covert the array to a string:
var myArray = myArray.toString();
and then search the string for the match. In your case, you are returning a pre-defined value, so that should work. It doesn't seem that you need to extract something from the array after a match is found. Which would require more processing.
if (typeof url === 'object') {//If data is an array
url = url.toString();
}

Json Array Object
Through Ajax I will get dynamic data which is not constant or similar data based on query data will change. But I want to display charts so I used chartjs where I need to pass array data. So I tried below code but whenever data changes that code will break.
I cannot paste complete JSON file so after parsing it looks like this
[{"brand":"DUNKIN' DONUTS KEURIG","volume":1.9,"value":571757},{"brand":"MC CAFE","volume":1.1,"value":265096}];
You can use Object.keys and specify the position number to get that value
var valueOne =[];
var valueTwo = [];
jsonData.forEach(function(e){
valueOne.push(e[Object.keys(e)[1]]);
valueTwo.push(e[Object.keys(e)[2]]);
})
It seems like what you're trying to do is conditionally populate an array based the data you are receiving. One solution might be for you to use a variable who's value is based on whether the value or price property exist on the object. For example, in your forEach loop:
const valueOne = [];
jsonData.forEach((e) => {
const val = typeof e.value !== undefined ? e.value : e.average;
valueOne.push(val);
})
In your jsonData.forEach loop you can test existence of element by using something like:
if (e['volume']===undefined) {
valueone.push(e.price);
} else {
valueone.push(e.volume);
}
And similar for valuetwo...
You could create an object with the keys of your first array element, and values corresponding to the arrays you are after:
var data = [{"brand":"DUNKIN' DONUTS KEURIG","volume":1.9,"value":571757},{"brand":"MC CAFE","volume":1.1,"value":265096}];
var splitArrays = Object.keys(data[0]).reduce((o, e) => {
o[e] = data.map(el => el[e]);
return o;
}, {});
// show the whole object
console.log(splitArrays);
// show the individual arrays
console.log("brand");
console.log(splitArrays.brand);
console.log("volume");
console.log(splitArrays.volume);
// etc
I'm trying to iterate over this json encoded array which is a string:
"{"":{"count":{"total":112,"open":0,
"solved":0,
"deleted":106,
"closed":6},
"average_time_open_in_minutes":206,
"tickets_fortnight_week_count":11,

An ajax call returns that string and i'm trying to only get the keys like: "app usage" and "Meter Offline" to return like so:
$.get('/ajax/ticket-and-notes-data.php', function (data) {
var problems = getProblems(data);
function getProblems(problems) {
var problemCategories = [];
$.each(JSON.parse(problems), function (key, value) {
if (key != "") {
problemCategories.push = key;
}
});
return problemCategories;
}
});
But I can't get the keys to go into the problemCategories.
I use this to set the categories in a highchart bubble chart and I will use more of the data from the string later.
I need to get this to work first.
The issue is in the way that you're using array.push. You should use array.push(item) instead of array.push = item.
I have an array members. This array has a name as the index (e.g. "John Smith") and an array with "degree" and "id", like so:
I have a search that fires on keyup action. It is supposed to search through the member names (the index) and then output the name of any matching members to the console:
function memberSearch(){
var $input = $("#guestsearch>input");
var val = $input.val();
console.log(val);
$.each(members, function(i,v){
if(i.indexOf(val)>-1){
console.log(members[i]);
}
})
}
However, this doesn't output anything except the search value val. Even if the $.each function is just console.log(i), nothing outputs.
If I manually type console.log(members) into console, the screenshot from above is the result.
members is populated by this segment of a function:
$.each(json.response.data[0].members, function(i,v){
var m = json.response.data[0].members[i];
var name = m.name;
if(name.typeof!=="undefined"&&name!=""&&name!=null&&name.length>0){
members[name] = [];
members[name]["degree"] = m.degree;
members[name]["id"] = m.id;
}
})
How can I make this search work?
If members is an object, which it looks like with the key/value pairs, you can use Object.keys(objVariable) to get the keys of an object to loop over and do your comparison/regex logic on.
Object.keys(members).forEach(function(name){
if (/* logic to match on name */) {
console.log(members[name]);
}
});
Otherwise if members is an array containing those objects...
var matchingUsers = members.filter(function(){
var username = Object.keys(this)[0];
return (/* match username to whatever */);
});
Then matchingUsers would be an array containing all the users that passed your criteria.
So close to nailing this but falling at the last hurdle... Need some clarification.
Basically, I want to load in the array value of a key in a given object as a variable, if other variable strings match.
Perhaps it's better if I give it some context:
js:
var ArraysObject = {
"new" : [
"http://productPageBanners/UK/2new/c0bkn201001u0000.jpg",
"http://productPageBanners/UK/2new/h0ihd60100000001.jpg",
"http://productPageBanners/UK/2new/l0flj20100000001.jpg",
"http://productPageBanners/UK/2new/m0lrt60100000001.jpg",
"http://productPageBanners/UK/2new/p0gps50106000001.jpg"
],
"knives" : [
"http://productPageBanners/UK/3aknives/c0bkn201001u0000.jpg",
"http://productPageBanners/UK/3aknives/n01pl20100000001.jpg"
]
};
var url = jQuery(location).attr('href'); // get the current url, outputs URL
var icatRef = url.split("/")[4]; // capture the icatRef from url, outputs ==>"knives"
// Get properties on the object ArraysObject as an array
var icatTitlesInObject = Object.keys(ArraysObject); // outputs the keys in object, i.e ==> ["new","knives"]
Then I want to check that if the indexOf that array is equal to the icatRef (pulled from the URL), then create a new variable which stores the relevant array from the correct key.
Something like:
if (icatsArray.indexOf() == icatRef) {
var currentarraytorandomise = ArraysObject.keys.this};
// if "knives" is the icatRef then currentarraytorandomise ==> [
// "http://productPageBanners/UK/3aknives/c0bkn201001u0000.jpg",
// "http://productPageBanners/UK/3aknives/n01pl20100000001.jpg"
// ]
However that last bit is wrong because currentarraytorandomise is undefined.
I hope that's clear! Quite new to OOP.
You're using indexOf incorrectly, try something like this:
var currentarraytorandomise, index = icatsArray.indexOf(icatRef);
if (index >= 0) {
currentarraytorandomise = ArraysObject[icatsArray[index]];
}
But you could just try to get the array directly:
ArraysObject[icatRef]
Without extracting keys or anything. If icatRef doesn't exist, you'll get undefined.
I'm using Backbone.js/Underscore.js to render a HTML table which filters as you type into a textbox. In this case it's a basic telephone directory.
The content for the table comes from a Collection populated by a JSON file.
A basic example of the JSON file is below:
[{
"Name":"Sales and Services",
"Department":"Small Business",
"Extension":"45446",
},
{
"Name":"Technical Support",
"Department":"Small Business",
"Extension":"18800",
},
{
"Name":"Research and Development",
"Department":"Mid Market",
"Extension":"75752",
}]
I convert the text box value to lower case and then pass it's value along with the Collection to this function, I then assign the returned value to a new Collection and use that to re-render the page.
filterTable = function(collection, filterValue) {
var filteredCollection;
if (filterValue === "") {
return collection.toJSON();
}
return filteredCollection = collection.filter(function(data) {
return _.some(_.values(data.toJSON()), function(value) {
value = (!isNaN(value) ? value.toString() : value.toLowerCase());
return value.indexOf(filterValue) >= 0;
});
});
};
The trouble is that the function is literal. To find the "Sales and Services" department from my example I'd have to type exactly that, or maybe just "Sales" or "Services". I couldn't type "sal serv" and still find it which is what I want to be able to do.
I've already written some javascript that seems pretty reliable at dividing up the text into an array of Words (now updated to code in use).
toWords = function(text) {
text = text.toLowerCase();
text = text.replace(/[^A-Za-z_0-9#.]/g, ' ');
text = text.replace(/[\s]+/g, ' ').replace(/\s\s*$/, '');
text = text.split(new RegExp("\\s+"));
var newsplit = [];
for (var index in text) {
if (text[index]) {
newsplit.push(text[index]);
};
};
text = newsplit;
return text;
};
I want to loop through each word in the "split" array and check to see if each word exists in one of the key/values. As long as all words exist then it would pass the truth iterator and get added to the Collection and rendered in the table.
So in my example if I typed "sal serv" it would find that both of those strings exist within the Name of the first item and it would be returned.
However if I typed "sales business" this would not be returned as although both the values do appear in that item, the same two words do not exist in the Name section.
I'm just not sure how to write this in Backbone/Underscore, or even if this is the best way to do it. I looked at the documentation and wasn't sure what function would be easiest.
I hope this makes sense. I'm a little new to Javascript and I realise I've dived into the deep-end but learning is the fun part ;-)
I can provide more code or maybe a JSFiddle if needed.
Using underscore's any and all make this relatively easy. Here's the gist of it:
var toWords = function(text) {
//Do any fancy cleanup and split to words
//I'm just doing a simple split by spaces.
return text.toLowerCase().split(/\s+/);
};
var partialMatch = function(original, fragment) {
//get the words of each input string
var origWords = toWords(original + ""), //force to string
fragWords = toWords(fragment);
//if all words in the fragment match any of the original words,
//returns true, otherwise false
return _.all(fragWords, function(frag) {
return _.any(origWords, function(orig) {
return orig && orig.indexOf(frag) >= 0;
});
});
};
//here's your original filterTable function slightly simplified
var filterTable = function(collection, filterValue) {
if (filterValue === "") {
return collection.toJSON();
}
return collection.filter(function(data) {
return _.some(_.values(data.toJSON()), function(value) {
return partialMatch(value, filterValue);
});
});
};
Note: This method is computationally pretty inefficient, as it involves first looping over all the items in the collection, then all the fields of each item, then all words in that item value. In addition there are a few nested functions declared inside loops, so the memory footprint is not optimal. If you have a small set of data, that should be OK, but if needed, there's a number of optimizations that can be done. I might come back later and edit this a bit, if I have time.
