How can I convert a DOM element to a jQuery element?
提问by Tanmoy
I am creating an element with document.createElement(). Now how can I pass it to a function that only takes a Jquery object?
我正在使用 document.createElement() 创建一个元素。现在我怎样才能将它传递给一个只接受 Jquery 对象的函数?
$("#id")
I can not use it, as the element has not been rendered in the page yet.
我无法使用它,因为该元素尚未在页面中呈现。

var elm = document.createElement("div");
var jelm = $(elm);//convert to jQuery Element
var htmlElm = jelm[0];//convert to HTML Element

What about constructing the element using jQuery? e.g.
使用 jQuery 构造元素怎么样?例如
$("<div></div>")
creates a new div element, ready to be added to the page. Can be shortened further to
创建一个新的 div 元素,准备添加到页面中。可以进一步缩短为
$("<div>")
then you can chain on commands that you need, set up event handlers and append it to the DOM. For example
然后您可以链接您需要的命令,设置事件处理程序并将其附加到 DOM。例如
$('<div id="myid">Div Content</div>')
.bind('click', function(e) { /* event handler here */ })
.appendTo('#myOtherDiv');

So far best solution that I've made:
到目前为止,我提出的最佳解决方案:
function convertHtmlToJQueryObject(html){
var htmlDOMObject = new DOMParser().parseFromString(html, "text/html");
return $(htmlDOMObject.documentElement);
}
