列出几个"GM_listValues"，调用一个函数以删除自己 [英] Make List of several "GM_listValues", calling a function to remove themselves

问题描述

我目前正在使用Greasemonkey脚本，该脚本允许将用户添加到忽略列表，这将阻止其注释的呈现.

I'm currently working on a Greasemonkey script, that allows to add users to an ignore list which will block their comments from being rendered.

我通过"GM_setValue"存储其用户ID.一切正常，但是我在渲染脚本的管理您的禁止列表"部分时遇到问题，请原谅用户.

I store their userID via "GM_setValue". Everything is working just fine but I have problems to render the "Manage your ban-list" part of my script to pardon a user.

我遇到麻烦的代码块:

var banList = GM_listValues(); // Array of Usernames
var manageBans = $("#content_content"); //The <div> I want to render the Banlist in.
manageBans.append("<h4>Manage ignorelist</h4>");


for (var i=0; i < banList.length; i++) {
    var currentUser = banList[i];   

    manageBans.append($('<b>'+currentUser+'</b><a href ="javascript:void(null)"><img src="/redaktion/style/delete.png" width="16" height="16" alt="unblock_user"></a></br>').click(function(){ unbanUser(currentUser)}));
}


var unbanUser = function(name) {                    
        GM_deleteValue(name);
};      

因此，基本上这可以正常工作，所有被禁止的用户都显示在列表中，我可以单击以取消禁止.但是，一旦我单击任何一个用户来调用"unbanUser"，列表中的最后一个用户就会被禁止，而不是我单击的那个用户.

So basically this is working fine, all banned users are rendered in a list and I can click to unban. But once I click at any user to call "unbanUser", the last user in the list gets unbanned and not the one I clicked at.

我猜变量"currentUser"始终是列表上的姓，我有点希望它成为for循环完成后每个用户的固定链接. 这是一项微不足道的任务，但我找不到合适的解决方案.

I guess the variable "currentUser" is always the last name on the list, I kinda wanted it to be a fix link for each user after the for-loop is finished. It's quite a trivial task but I don't find a proper solution.

您对我有提示吗? 问候

Do you have a hint for me? Greets

推荐答案

在循环结束时，currentUser每次迭代都会被覆盖.在click函数内部，您引用的是currentUser，它等于currentUser的最后一个定义.

At the end of the loop, currentUser keeps getting overwritten on each iteration. Inside the click function, you're referring to currentUser, which equals the last definition of currentUser.

要解决此问题，请使用闭包:

To fix it, make use of closures:

function doSomething(currentUser) {
    manageBans.append($('<b>'+currentUser+'</b><a href="javascript:void(null)"><img src="/redaktion/style/delete.png" width="16" height="16" alt="unblock_user"></a></br>').click(function(){
        unbanUser(currentUser)
    }));
}

for (var i=0; i < banList.length; i++) {
    doSomething(banList[i]);
}
