我有一个 livecore 网站,我正在尝试制作该网站的小工具以在其他网站上显示它的一部分,我面临的问题是如何将我的代码(JavaScript 和 CSS)与我的主机站点的代码隔离开来小工具。我使用这样的“匿名函数”:
(function() {
// Localize jQuery variable
var jQuery;
/******** Load jQuery if not present *********/
if (window.jQuery === undefined || window.jQuery.fn.jquery !== '1.8.3') {
var script_tag = document.createElement('script');
script_tag.setAttribute("type","text/javascript");
script_tag.setAttribute("src",
"http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js");
if (script_tag.readyState) {
script_tag.onreadystatechange = function () { // For old versions of IE
if (this.readyState == 'complete' || this.readyState == 'loaded') {
scriptLoadHandler();
}
};
} else { // Other browsers
script_tag.onload = scriptLoadHandler;
}
// Try to find the head, otherwise default to the documentElement
(document.getElementsByTagName("head")[0] || document.documentElement).appendChild(script_tag);
} else {
// The jQuery version on the window is the one we want to use
jQuery = window.jQuery;
main();
}
/******** Called once jQuery has loaded ******/
function scriptLoadHandler() {
// Restore $ and window.jQuery to their previous values and store the
// new jQuery in our local jQuery variable
jQuery = window.jQuery.noConflict(true);
// Call our main function
main();
}
/******** Our main function ********/
function main() {
jQuery(document).ready(function($) {
/******* Load CSS *******/
var css_link = $("<link>", {
rel: "stylesheet",
type: "text/css",
href: "http://localhost/aaa/widget/widget.css"
});
css_link.appendTo('head');
var txt;
txt='<div id="wrapper">';
txt=txt+'<ul class="tabs">';
txt=txt+'<li id="fixtures_tab"><a href="#fixtures">All</a></li>';
txt=txt+'<li id="live_tab"><a href="#live">Live</a></li>';
txt=txt+'<li id="finished_tab"><a href="#finished">finished</a></li>';
txt=txt+'<li id="program_tab"><a href="#program">Program</a></li>';
txt=txt+'<li id="postpond_tab"><a href="#postpond">Postpond</a></li>';
txt=txt+'<li id="selected_tab"><a id="f" href="#fav">Selected (0)</a></li>';
txt=txt+'</ul>';
txt=txt+'<div class="tab-container">';
txt=txt+'<div id="fixtures" class="tab-content"><script type="text/javascript">get_All_Today_Matches();</script></div>';
txt=txt+'<div id="live" class="tab-content"><script type="text/javascript"></script></div>';
txt=txt+'<div id="finished" class="tab-content"><script type="text/javascript"></script></div>';
txt=txt+'<div id="program" class="tab-content"><script type="text/javascript"></script></div>';
txt=txt+'<div id="postpond" class="tab-content"><script type="text/javascript"></script></div>';
txt=txt+'<div id="fav" class="tab-content"><script type="text/javascript"></script></div>';
txt=txt+'</div>';
txt=txt+'</div>';
$('#widget-container').html(txt);
});
}
})(); // We call our anonymous function immediately
JQuery 一切正常,但 CSS 不正常(CSS 文件已加载并且工作正常,但一些托管站点 CSS 影响了我的 CSS)我无法控制托管站点 CSS,我认为我已经隔离了我的代码使用匿名函数很好,但为什么我的 CSS 会受到网站原始 CSS 的影响?请帮帮我,我已经有一段时间了
