constructor() { // how to query the DOM element from here? }
}虽然看过几个答案，但是没看明白，自己动手也都失败了，求教

First install jquery
tsd install jquery --save
or
typings install dt~jquery --global --save
Write in the header of the ts file you need to use
declare var $: any;
This way you can use jquery in your ts file
Like it, but it is not recommended to use Jquery in angular2, it is easy to be contaminated
ng2 Don’t use jquery, there is no needIf you pass the dom, just specify it #content in the template
#content
