why javascript permits $ for name of functions?

由 我的未来我决定 提交于 2019-12-13 20:18:35
问题 I am starting to love jQuery but as PHP developer I hate using that $().stuff as everyone know $ in PHP marks variables. I guess jQuery in javascript declares a function like this function $(element) {/*stuff*/} Does javascripts permits $ as the name of a func? Is that a good behaviour? I knew only standard [0-9a-zA-Z_] could be the name of funcs/vars. Am I missing something? Thanks 回答1: You can do var whatever = $.noConflict(); now you can use whatever(..) instead of $(...) documentation at

Understanding rules for parsing tokens in foreign content

由 。_饼干妹妹 提交于 2019-12-13 18:00:26
问题 I have a question it is related to the stage of executing instructions in the condition. I do not quite understand what each instruction means and when it is executed. Examples with the help of UA would be very helpful in this case. Here is a piece from specification: A start tag one of the following: b, big, blockquote, body, br, center, code, dd, div "dl", "dt", "em", "embed", "h1", "h2", "h3", "h4", "h5", "h6", "head", "hr", "i", "img", "li", "listing", "menu", "meta", "nobr", "ol", "p",

AngularJS directives as “custom” HTML tags: isn't this dangerous and may conflict with future HTML versions?

由 邮差的信 提交于 2019-12-13 15:26:52
问题 I'm currently reading a lot about different JS frameworks (EmberJS, AngularJS, etc.). On first sight, I loved AngularJS' idea of using directives like custom HTML tags: <mytag>...</mytag> But isn't this dangerous? If I define a lot of such tags, then there's a high likelihood that a future HTML spec may also define one of my custom tags, but with a whole other meaning! I know that custom tags may be allowed by the HTML spec itself: http://w3c.github.io/webcomponents/spec/custom/ But at the

object property order between integer indexes, symbols and strings

由 孤街浪徒 提交于 2019-12-13 10:26:59
问题 In recent ECMAScript, is it possible to obtain a list of all properties of an object in creation order [1] ? There are two issues that i could not find to be exposed by specification [2] . I am asking whether i missed something. Is either possible to obtain? Creation order of integer indexes Order of integer indexes, symbols and strings between another In other words, given an object coming from an object literal { "propName": 0, [Symbol.for("identifier")]: 0, "0": 0 } Is it possible to

Why fetch Body object can be read only once?

由 為{幸葍}努か 提交于 2019-12-12 16:27:08
问题 The fetch specification states that the readable stream Body contains the Body.bodyUsed flag which is initially set to false and then is set to true with a call of any parsing method. Here's an example: fetch('/some/path', (res) => { // res.body.bodyUsed === false res.json(); // res.body.bodyUsed === true }); If you try to call a method like res.json() or res.text() once again, an exception is thrown. The question is : why that behavior is used? Why not to allow parsing that readable stream

Selenium Can't Find 'spec' Folder

由 ≯℡__Kan透↙ 提交于 2019-12-12 15:16:40
问题 So I'm attempting to set up my local system to help finish off an existing project from an employer who uses only rails. They want me to primarily focus on rspec testing as the project is nearly functional and I need to flesh out the things they've missed. However, I cannot get 'rake spec' to build my test folder. As it is, the test folder contains a few basic user login tests using Selenium (I didn't write them). Here is the trace from the error: /opt/local/lib/ruby/gems/1.8/gems/selenium

For instance, to make an exe with (I am using pyjnius for handling the sikuli-standalone jar): # test.py import os import sys # set the classpath so java can find the code I want to work with sikuli_jar = '/sikuli-api.standalone-1.0.3-Pre-1.jar' jarpath = os.path.dirname(os.path.realpath(__file__)) + sikuli_jar os.environ['CLASSPATH'] = jarpath # now load a java class from jnius import
