stringify

问题 I don't know if the question is very accurate but I'm trying to change a value from a localstorage array. This is what my localstorage looks like: [{"id":"item-1","href":"google.com","icon":"google.com"}, {"id":"item-2","href":"youtube.com","icon":"youtube.com"}, {"id":"item-3","href":"google.com","icon":"google.com"}, {"id":"item-4","href":"google.com","icon":"google.com"}, {"id":"item-5","href":"youtube.com","icon":"youtube.com"}, {"id":"item-6","href":"asos.com","icon":"asos.com"}, {"id":

问题 I am currently using AJAX with JQuery to send json to an API server. However, there seems to be an issue with a server that is escaping the JSON string when I use JSON.stringify() but on another server when using the exact same code it works without any problems. Here is an example of the Javascript object that I am using stringify on: {"jsonrpc":"2.0","method":"get_contacts","params":["4345ert343t34t34t4e564", {"campaigns":["AI5D"]}],"id":1} I am working from the examples here https://github

问题 In my code, all of the info from a Postgres table row are stringified when a specific rowID is selected. var jsonRes = result.message.rows; document.getElementById('panel').innerHTML = '<pre>' + JSON.stringify(jsonRes[0], null, "\t") + '</pre>' The result looks something like this: { "ogc_fid": 143667, "relkey": 288007, "acct": "000487000A0010000", "recacs": "12.5495 AC", "shape_star": 547131.567383, "shape_stle": 3518.469618, "objectid": 307755, "zone_dist": "MU-3", "pd_num": null, "council

问题 I want to parse an object into client-side javascript through Jade. Normally this would work: script var object = JSON.parse(#{JSON.stringify(object)}); but my object is circular and I need to do this script var object = CircularJSON.parse(#{CircularJSON.stringify(object)}); but it throws the error Cannot call method 'stringify' of undefined which I guess is because Jade doesn't recognise my CircularJSON method. Any way to make it? 回答1: It could be required and passed in the locals response

问题 In localstorage I have key ' results ' with this values : [{"id":"item-1","href":"google.com","icon":"google.com"}, {"id":"item-2","href":"youtube.com","icon":"youtube.com"}, {"id":"item-3","href":"google.com","icon":"google.com"}, {"id":"item-4","href":"google.com","icon":"google.com"}, {"id":"item-5","href":"youtube.com","icon":"youtube.com"}, {"id":"item-6","href":"asos.com","icon":"asos.com"}, {"id":"item-7","href":"google.com","icon":"google.com"}, {"id":"item-8","href":"mcdonalds.com",

问题 Memory usage is quite critical in my application. Therefore I have specific asserts that check for the memory size at compile time and give a static_assert if the size is different from what we considered correct before. I have defined a macro like this: #define CHECKMEM(mytype, size) static_assert((sizeof(objectType) == size)), "Size incorrect for " #mytype "!"); This macro makes it very easy to write this: CHECKMEM(Book,144); CHECKMEM(Library,80); The problem is that when this static_assert

问题 Im trying to pass a mulitidimensional Javascript array to another page on my site by: using JSON.stringify on the array assigning the resultant value to an input field posting that field to the second page using json_decode on the posted value then var_dump to test (echo'ing the posted variable directly just to see if it came through at all) Javascript on page one: var JSONstr = JSON.stringify(fullInfoArray); document.getElementById('JSONfullInfoArray').value= JSONstr; php on page two: $data

问题 So, I was interested to find that JSON.stringify reduces a RegExp to an empty object-literal (fiddle): JSON.stringify(/^[0-9]+$/) // "{}" Is this behavior expected? I realize that a RegExp is an object with no properties to serialize. That said, dates are objects too; yet JSON.stringify() manages to produce a meaningful string: JSON.stringify(new Date) // "2014-07-03T13:42:47.905Z" I would have hoped that JSON would give RegExp the same consideration by using RegExp.prototype. toString() .

问题 I need a function building a JSON valid string from any argument but : avoiding recursivity problem by not adding objects twice avoiding call stack size problem by truncating past a given depth Generally it should be able to process big objects, at the cost of truncating them. As reference, this code fails : var json = JSON.stringify(window); Avoiding recursivity problem is simple enough : var seen = []; return JSON.stringify(o, function(_, value) { if (typeof value === 'object' && value !==
