我该如何处理这段文字？

Question

的XPath是

//*[@id="main-results"]/div[3]/div/div/div[3]/div/div[1]/div[2]/div[1]/div[1]/div/text() 

实际HTML是

<div class="medium-item-price"><span class="denominator">$</span>699.99</div> 

我想换个699.99至另一号码。

$(document).getElementByClassName("medium-item-price").Value = 100; 

Answer 1

你可以像下面这样做。

$('.medium-item-price').contents().last()[0].textContent='100';

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<div class="medium-item-price"> 
 
    <span class="denominator">$</span> 
 
    699.99 
 
</div>

Answer 2

不应该这样就足够了？只要注意这将删除.denominator，并用所需的值替换内部文本。

$('.medium-item-price').text('$1') 

$('.medium-item-price').text('$1');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script> 
 
<div class="medium-item-price"><span class="denominator">$</span>699.99</div>

Answer 3

请试试这个代码。这里的jsfiddle：https://jsfiddle.net/stLg13h0/

console.log(document.getElementsByClassName("medium-item-price")[0].innerText); 
 

 
document.getElementsByClassName("medium-item-price")[0].innerText = 700;

<div class="medium-item-price"><span class="denominator">$</span>699.99</div>
