The difference between assigning event handlers with bind() and each() in jQuery?

女生的网名这么多〃 提交于 2019-12-04 16:09:41
can someone tell me what the difference between assigning event handlers using bind(): $(function(){ $('someElement') .bind('mouseover',function(e) { $(this).css({ //change color }); }) .bind('mouseout',function(e) { $(this).css({ //return to previous state }); }) .bind('click',function(e) { $(this).css({ //do smth. }); }) }); and using each() for the same task: $('someElement').each(function(){ $(this).mouseover(function(){$(this).css({/*change color*/}) .mouseout(function(){$(this).css({/*return to previous state*/}); }); }); }); thank you.

Closed . This question is opinion-based. It is not currently accepting answers. Learn more . Want to improve this question? Update the question so it can be answered with facts and citations by editing this post . Closed 6 years ago . Should we prefer the for-each loop instead of the traditional for-loops? Is the while-loop advantageous? List<String> names = Arrays.asList("John", "Jeff", "Mary", "Elise"); //for-each loop for(String name: names){ log(name); } //traditional for-loop for(int index=0; index < 10; ++index){ log(names.get(index)); } //Iterator while Iterator<String> iter1 = names

i am building an jQuery plugin, but i want to use objects in the options var, how can i loop this with the jQuery each? plugin options var var defaults = { test: 'yes', //css/classes type: { minvalue: '100', maxvalue: '200', name: 'id1' }, type: { minvalue: '200', maxvalue: '300', name: 'id2' }, type: { minvalue: '300', maxvalue: '400', name: 'id3' } }; $.each(defaults, function(key, value) { alert(key + ': ' + value); }); With your example it is a bit difficult to figure what exactly you are trying to do, but if you want to use arrays and $.each , you could do this: var defaults = { test:

STL 简介,标准模板库

这篇文章是关于C++语言的一个新的扩展——标准模板库的(Standard Template Library),也叫STL。 当我第一次打算写一篇关于STL的文章的时候,我不得不承认我当时低估了这个话题的深度和广度。有很多内容要含盖,也有很多详细描述STL的书。因此我重新考虑了一下我原来的想法。我为什么要写这篇文章,又为什么要投稿呢?这会有什麽用呢?有再来一篇关于STL的文章的必要吗? 当我翻开Musser and Saini的页时,我看到了编程时代在我面前消融。我能看到深夜消失了, 目标软件工程出现了。我看到了可维护的代码。一年过去了,我使用STL写的软件仍然很容易维护。 让人吃惊的是其他人可以没有我而维护的很好! 然而,我也记得在一开始的时候很难弄懂那些技术术语。一次,我买了Musser&Saini,每件事都依次出现,但是在那以前我最渴望得到的东西是一些好的例子。 当我开始的时候,作为C++一部分的Stroustrup还没出来,它覆盖了STL。 因此我想写一篇关于一个STL程序员的真实生活的文章可能会有用。如果我手上有一些好的例子的话,特别是象这样的新题目,我会学的更快。 另外一件事是STL应该很好用。因此,理论上说,我们应该可以马上开始使用STL。 什麽是STL呢?STL就是Standard Template Library,标准模板库

what does “return this.each()” do in jQuery?

回眸只為那壹抹淺笑 提交于 2019-12-04 10:43:24
问题 I'm looking at a jQuery plugin, which has a single function. After setting up the appropriate defaults though a constructor argument the function defines a couple of helper functions, and then as the last part returns a call to this.each(), like so: return this.each(function() { //long method defined here }); I understand the use of this.each() in modifying matching DOM elements and such, but what does the return statement accomplish? Some sort of array of modified DOM elements, which can

Passing arguments to jQuery each function

冷暖自知 提交于 2019-12-04 10:36:54
问题 When using the jQuery "each" function, is there a way to pass arguments to the function that is called ? something.each(build); function build(vars) { } I know that I can simply do the following, but I was wondering if there is a way in which arguments can be passed directly. something.each(function() { build(vars); ); 回答1: You can accomplish the above using a closure. The .each function takes as an argument a function with two arguments, index and element. You can call a function that

setTimeout inside $.each()

问题 ok, so I've got this code: $(this).find('article.loading').each( function(i) { var el = this; setTimeout(function () { $(el).replaceWith($('#dumpster article:first')); }, speed); }); I want to replace each element with another but I want a delay between each replace. I can't figure out why this isn't working, it just replaces all of them after one timeout. Any ideas? Thanks. 回答1: You are looping through the elements and adding a timer to each with the same configuration. Essentially a new
