我想创建使用JavaScript和jQuery在Salesforce控件方法“noConflict”,我被套牢了错误:遗漏的类型错误:无法调用未定义遗漏的类型错误:无法调用未定义
法“noConflict”下面是我的代码,我使用
(function() {
// Localize jQuery variable
var $j;
/******** Load jQuery if not present *********/
if (window.jQuery === undefined || window.jQuery.fn.jquery !== '1.4.2') {
var script_tag = document.createElement('script');
script_tag.setAttribute("type","text/javascript");
script_tag.setAttribute("src",
"https://ap1.salesforce.com/resource/go/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 {
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
$j = 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
$j = window.jQuery.noConflict(true);
// Call our main function
main();
}
/******** Our main function ********/
function main() {
$j(document).ready(function($) {
/******* Load CSS *******/
var css_link = $("<link>", {
rel: "stylesheet",
type: "text/css",
href: "style.css"
});
css_link.appendTo('head');
/******* Load HTML *******/
var jsonp_url = "http://al.smeuh.org/cgi-bin/webwidget_tutorial.py?callback=?";
$.getJSON(jsonp_url, function(data) {
$('#example-widget-container').html("This data comes from another server: " + data.html);
});
});
}
})(); // We call our anonymous function immediately
在浏览器控制台错误指向到scriptLoadHandler功能的第一道防线。
你有没有在你的 –
页面包括jQuery的是我做的,我动态,包括它通过检查与如果现有的或没有,你可以看到它在上述代码的第三行。 –
当我打开https://ap1.salesforce.com/resource/go/jquery.min.js它似乎不包含jQuery代码。你有没有尝试从其他地方包括jquery? – Reason
