In China, it should be, because China is in the GMT + 8 hours ). The C # Time is recorded in units of ticks. the literal translation is the CPU time "tick", which is a unit smaller than milliseconds. In the conversion between the two, pay attention to the conversion of the start time a

Converts a json string to a json object. During data transmission, json is transmitted in the form of text, that is, strings, while JS operates on JSON objects. Therefore, mutual conversion between JSON objects and JSON strings is critical. For example: JSON string:Var str1 = '{"name": "cxh", "sex": "man "}';JSON object:Var str2 = {"name": "cxh", "sex": "man "}; 1. convert a JSON string to a JSON object To use str1 above, you must use the following m

This article mainly introduces how to convert array elements into strings in JavaScript, which is the basic knowledge in JS learning, for more information, see slice (): Source code: ​Click the button to extract the second and the third elements from the array.​Try it​《script》function myFunction(){var fruits = ["Banana", "Orange", "Lemon", "Apple", "Mango"];var citrus = fruits.slice(1,3);var x=document.ge

URL of the Dataurl format is obtained from the File,blob object, and then the dataurl image data is drawn to the canvasfunction (dataurl){ varnew Image(); function(){ canvas.drawImage(img); }; img.src = dataurl;});Different methods are used to construct different types of URLs (Dataurl, Objecturl (Bloburl), Filesystemurl, respectively). This is not described here, but only in the case of Dataurl.Filesystemurl does not refer to the form of a local file URL (file:///...), but r

In daily development, such a situation often arises. There are a number of functions that are generic. And every JavaScript is written once, which is very disturbing for maintenance. Therefore, the public functions need to be written in an external JS file. In this case, we need to introduce external public files. The following is the introduction of external public JS files in the JavaScript component in t

These two methods are mainly used to supplement the toQueryParams and Object toQueryString methods in the Sring section previously skipped in Prototype analysis. 1. Extract parameters from the URL. Has the following strings: Var linkURL = 'HTTP: // localhost: 8080/String/string_6.html? Nickname = xiaoxi mountain age = 24 # id1 '; For a real URL address, you can use js to read relevant information in location to obtain some information. The following lists some information: The Code is as fo

JS is a very magical language, the internal system of many functions can help us make a number (into) system conversion; JS can be directly used in the 16 system; var a = 0xFF; 255 Converts arbitrary feed strings to decimal, such as binary, octal, hexadecimal, and number two, which is the most commonly used conversion to integer decimal; The code is as follows: parseint ("11", 2); 3 2-in-turn 10-in-system parseint ("77", 8); 63 8-in-turn 10-in-system parseint ("AF", 16); 175 16-in-turn 10

The jquery object is the object that is generated after the DOM object is wrapped through jquery. jquery objects are unique to jquery, which can use the methods in jquery, but cannot use DOM methods, such as: $ ("#img"). attr ("src", "test.jpg"); The $ ("#img") here is the JQuery object. Dom objects are some of the object operations inherent to JavaScript. DOM objects can use the intrinsic methods of JavaScript
