javascript - jquery 选择文本

Question

<div>select this<strong>dfdfdf</strong></div>
<div><span>something</span>select this<strong>dfdfdf</strong></div>

我如何使用 jquery 或仅使用 javascript 来选择 div 标签的值但不包含任何子元素

//output
select this

Answer 1

$("div").contents().each(function(i) {
    //the function is applied on the node. 
    //therefore, the `this` keyword is the current node.
    //check if the current element is a text node, if so do something with it
});
