我尝试使用 PHP 的 Twitter API 并创建了一个部分，用户可以在其中了解建议关注的人...
这是我的文件 getSuggestionSlug.php 的源代码:
<?php
include "methods.php";
oauthVerify();
if(isset($_GET["slug"]) && !empty($_GET["slug"]))
{
$return = (array) getSuggestionSlug($_GET["slug"]);
}
else
{
header("Location: getSuggestion.php");
}
?>

实例可以在我的网站上找到here .
虽然我的 script.js 缩减为相关部分如下:
var showControls = function(name, screen_name){
console.log(name + " " + screen_name);
$("#" + screen_name).attr("style", "margin-left: 100px; margin-top: 5%; height: 150px; font-size: large; cursor: pointer; padding: 1%;");
$("#" + screen_name).html(name + "<br /><br /><a href='userShow.php?screen_name=" + screen_name + "'><button class='btn btn-primary'>Get Details</button></a> <a href='makeFriend.php?screen_name=" + screen_name + "'><button class='btn btn-primary'>Make Friend</button></a>")
};
我的问题是悬停在框上时出现的按钮不会打开任何链接，我使用 <a> 专门解决了这个问题标签，我也尝试使用 window.location结果也是一样的。
关于为什么会发生以及我该如何解决的任何想法？
最佳答案
这与当您将鼠标悬停在按钮上时函数 showControls 被多次调用这一事实有关。每次您这样做时，它都会销毁并重新创建按钮。
举个例子试试这个。它只在第一次创建控件。在这种情况下它有效(无论如何一次)。
var first = true;
var showControls = function(name, screen_name){
if(first) {
first = false;
console.log(name + " " + screen_name);
$("#" + screen_name).attr("style", "margin-left: 100px; margin-top: 5%; height: 150px; font-size: large; cursor: pointer; padding: 1%;");
$("#" + screen_name).html(name + "<br /><br /><a href='userShow.php?screen_name=" + screen_name + "'><button class='btn btn-primary'>Get Details</button></a> <a href='makeFriend.php?screen_name=" + screen_name + "'><button class='btn btn-primary'>Make Friend</button></a>")
}
};
也许一个解决方案是记录已经存在的控件，然后仅在它们不存在时才创建它们。
