dynamic

问题 There are lots of questions that seem to be asking this, but in the end all they want is to attach .click events and not .each and so the generally accepted answer in all of them include $("body").on("click", ".selector", function(){}); and this is definitely not what I want. I have some generated inputs and I need to change the value of each one at the same time. Normally I would $(".inputs").each(function(){$(this).val("new-value")}; or something along those lines, however, I can't because

问题 I am writing an application and it needs tables to be created dynamically.

问题 this is what I need $a=array('folder'=>'anyfolder','filename'=>'anyfilename','filedata'=>'anyfiledata'); I need to create a variable $zip with compressed data from $a and output this $zip into browser window with header('Content-type: application/octetstream'); echo $zip; All libs that I found, they pack files and create zip files physically on disk. I need to do it dynamically, using memory. Is there any examples of how to do it using pure php's zlib and without studying the zip format

问题 New coder here and would really appreciate your help with a problem that's got me stumped. I'd like to write code that will recognize the link that applies to the current page and applies a different CSS style to that current link. I've researched this problem and have found that it's best accomplished using jQuery to identify the current link and then apply a new class to it (e.g., ".current"). However, when I've tried to implement this on the site it hasn't worked. This is the HTML I'm

问题 I have a VB6 application where I'd like to have a consistent behavior among its controls application-wide. One of the behaviors, for example, would be highlighting a text box when it gains focus and removing the highlight when it loses focus. I'd like this to happen on every form. What I'm trying to do is have one sub procedure that can be called by all forms when they load that will make this behavior happen. That way, I don't have to manually code for each individual text box to make it

问题 Is it possible to use one fragment in a viewpager multiple times? I am trying to build a dynamically updated UI using ViewPager. I want to use the same design, basically the same fragment with different data for every page, like a listview adapter. 回答1: You can instantiate the same Fragment class for every page in your ViewPager, passing the position of the ViewPager to control what to display. Something like that: public class MyFragment extends Fragment { private int mIndex; public

问题 What I am trying to do is automate the process of going live with websites. These websites are all dynamically created using htaccess, so here is an example: RewriteCond %{ENV:REDIRECT_STATUS} ^$ RewriteCond %{HTTP_HOST} ^(www\.)?domain\.com$ [NC] RewriteRule ^(.*)$ /folder%{REQUEST_URI}?%{QUERY_STRING} [QSA,L] What I do is add a domain alias for domain.com , and then point it to my server IP and the htaccess file makes it view what is in the /folder. It works fine but we are planning to have

问题 I'm new in typescript, and i'm trying to rewrite our application from es2016 to typescript. My task is to have a class with data property and make each element from data object available as class property. I get stuck on this javascript code: for(let key in this.data) { Object.defineProperty(this, key, { get: function(value:any) { return this.data[key]; }, set: function(value:any) { if (this.data[key] !== value) { this.data[key] = value; this.updatedKeys.push(key); } }, }); } It is pretty
