问题 I have converted multiple swf files using google swiffy v5.2 and will have my new animations displayed on many different pages, most of which I do not have control of or access to. In order for the animation to work it needs the swiffy's runtime.js file, which might look something like this on the page: <script src="https://www.gstatic.com/swiffy/v5.2/runtime.js"></script> The problem arises when I either have multiple instances of the animation on the same page or a client has this runtime

问题 based on my question: https://stackoverflow.com/a/40661953/2392461, i open a new question with sample data. I want to merge/reduce this: var array = [{ 'key1': { 'key11': 0, 'key12': 1 }, 'key2': 0, 'key3': { 'key31': [1, 2], 'key32': { 'key321': 3, 'key322': [1, 2] } }, 'key4': 'test' }, { 'key1': { 'key11': 1, 'key12': 9 }, 'key2': 2, 'key3': { 'key31': [4, 3], 'key32': { 'key321': 6, 'key322': [8, 9] } }, 'key4': 'test' }, { 'key1': { 'key11': 3, 'key12': 4 }, 'key2': 7, 'key3': { 'key31':

问题 Searched and tried and no luck so far. var newUsers = [{name: 'rich', id: 25}, {name: 'lauren', id: 35}, {name: 'dave', id: 28} ] var likedUsers = [{name: 'derek', id: 39}, {name: 'rich', id: 25}, {name: 'brian', id: 38} ] What I want returned is: var leftUsers = [{name: 'lauren', id: 35}, {name: 'dave', id: 28} ] basically without the rich object as this is a duplicate. I only care about the id key. I have tried: newUsers.forEach((nUser) => { likedUsers.forEach((lUser) => { if (nUser.id !==

问题 I currently have an array data structure that I iterate over like this, calling foo on each unique pair of elements. for(var i = 0; i < arr.length; i++) { for(var j = i + 1; j < arr.length; j++) { foo(arr[i], arr[j]); } } However, I've realized that I'd rather use an object instead of an array, since I can then add and remove elements by name very easily. However, I can't see an obvious way to iterate over such an object. The closest I can get is: for(i in obj) { for(j in obj) { foo(obj[i],

问题 I've array of objects oDataSet and aProperties object and I want to match the identical values that are found in aPropertis and and In oDataSet and create the aSelectedDataSet which in beginning is an empty object How it's recommend to do it in JS/Jquery Note: there shouldnt be any hardcoded property in the loops/solution to do the match the aProperties is contain this value but it can be change (and of course there should be match in the oData object...) For clarification Following is

问题 I am trying to figure out the architecture for the following app: The user is presented with a table. Each table cell has several fields the user will be filling in. There is a general submit button: when clicked on all the input data (along with some calculated data per cell based on the input values) should pass to a Django view. Here are the following questions: Can I organize the data structure as a set of objects in a way that each object will correspond to a table cell, whereas the

问题 I have a React project set up to fetch an Object from a Firebase database and render this to my page. However I do not know how to render the data properly. The data I am fetching looks like this: { "projects": { "0": { "title": "test", "function": "test2" }, "1": { "title": "test3", "function": "test4" } } } In the Chrome React Debugger I see this: <div> <Message key="0" data={function: "test2", title: "test", key: "0"}>...</Message> <Message key="1" data={function: "test4", title: "test3",

问题 I have an object like this: var myObj = { first: { sub: { level: "some text", level2: "some more text" }, sub2: { level3: "Something" } }, second: { stuff: "More stuff...lots of stuff" } } what I want to be able to do is say delete myObj.first.sub.level But I won't know what is being passed, or how many levels deep I need to go in order to remove the correct property, meaning it could simply be: Storage.removeItem('myObj.first'); // This is currently working Or something more complex: Storage

问题 Say I have the follow array of objects storing a single key\value pair: var someArray = [ {foo: 1}, {bar: 2} ]; I would like to flatten this array into a single object, where each key from the original objects become a property of the new single object like so: someObject = { foo: 1, bar: 2 } I will always have unique keys, and only ever one key\value pairing. I know if I loop over the array in a foreach, then I can only access the index and value of the item, e.g. 0: {foo: 1} I want to be
