如何使用jquery获取所有元素父项？

How to get all element parents using jquery? i want to save these parents in a variable so i can use later as a selector.
such as <div><a><img id="myImg"/></a></div>
GetParents('myImg'); will return "div a" something like that

如何使用jquery获取所有元素父项?我想将这些父节点保存在变量中,以便稍后可以用作选择器。例如

GetParents('myImg');将返回“div a”之类的东西

5 个解决方案

#1

/// Get an array of all the elements parents:

///获取父元素的所有元素的数组:

allParents = $("#myElement").parents("*")

/// Get the nested selector through an element's parents:

///通过元素的父项获取嵌套选择器:

function GetParents(id) {
    var parents = $("#" + id).parents("*");
    var selector = "";
    for (var i = parents.length-1; i >= 0; i--) {
        selector += parents[i].tagName + " ";
    }

    selector += "#" + id;

    return selector;
}

GetParents('myImage') will return your nested selector: HTML BODY DIV A #myImage

GetParents('myImage')将返回您的嵌套选择器:HTML BODY DIV AmyImage

Note sure why you'd want this but its reuseable as a selector.

#2

You don't need to grab their selectors, as you can use them directly with jQuery afterwards.

您不需要抓取他们的选择器,因为您可以在之后使用jQuery直接使用它们。

If you want to use all parents later, you can do something like:

如果您想稍后使用所有父母,您可以执行以下操作:

var parents = $("#element").parents();
for(var i = 0; i < parents.length; i++){
  $(parents[i]).dosomething();
}

#3

Every element has only one real parent. To access and save it, write the following:

每个元素只有一个真正的父元素。要访问和保存它,请写下以下内容:

myParent = $("#myElement").parent();

If you need the parents parents too, use .parents()

如果你也需要父母的父母,请使用.parents()

You can use parents() to get your immediate parent, and their parents on up the tree. you can also pass a selector as an arg to only get parents that match a certain criteria. For instance:

您可以使用parents()将您的直接父母和他们的父母放在树上。您还可以将选择器作为arg传递给仅获取符合特定条件的父级。例如:

$('#myelement').parents('[id$=container]')

to get all parents who have an id attribute whose value ends with the text "container"

获取具有id属性的所有父级,其值以文本“container”结尾

#5

You can get all the tags of an element's parents like this:

您可以像这样获取元素父项的所有标记:

var sParents = $('#myImg').parents('*').map(function() {                
      return this.tagName;
    }).get().join(' ');

you can also replace this.tagName with this.id for example or other attributes

您也可以使用this.id或其他属性替换this.tagName
