我只想访问h1的文本(在这种情况下为H1 title is here
),但它会打印所有内容。我尝试在.remove('.small-title')
之前添加text()
,但它不起作用。
<div class="modal-know>
<h1>
H1 title is here
<div class="small-title">
<a href="title-a">Click</a>
<a href="title-b">Click 2</a>
</div>
</h1>
</div>
Node.js代码
var newsTitle = $2('.modal-know h1').text(); // prints out everything
console.log(newsTitle);
答案 0 :(得分:0)
它说
包括他们的后代
这与jQuery .text()
的行为相同所以也许这个答案可以帮到你:jQuery: using .text() to retrieve only text not nested in child tags
这里有你测试的代码:
size_t length = 5;
int number = 0;
std::pair<std::vector<int>, std::vector<int>> pv(std::vector<int>(length, number), std::vector<int>(length, number));
*在您的代码示例中缺少&#34;在div模态知识类
let newsTitle = $('.modal-know h1').contents()[0].nodeValue;
// solution 2:
// .clone() //clone the element
// .children() //select all the children
// .remove() //remove all the children
// .end() //again go back to selected element
// .text(); // prints out everything
//solution 3:
// .contents().filter(function(){
// return this.nodeType == 3;
// })[0].nodeValue;
console.log(newsTitle);
