使用javascript

Question

我在page0.html中有两个标签。我想在page1.html中显示哪个标签被点击了：

<a href="page1.html" target="_blank">A</a>
<a href="page1.html" target="_blank">B</a>

我想将page1.html看起来像：

  

按下链接A

     

或

     

链接B被按下了。

可以使用Javascript吗？或者我应该使用其他东西吗？

非常感谢

Answer 1

您可以添加哈希到url（href）并通过foreach (var course in customerInDb.CoursesEnrolled) { _context.Entry(course).State = System.Data.Entity.EntityState.Unchanged; }

进行访问

page0.html

window.location.hash

page1.html

<a href="page1.html#A" target="_blank">A</a>
<a href="page1.html#B" target="_blank">B</a>

Answer 2

您还可以在page0.html

中使用?

<a href="page1.html?a" target="_blank">A</a>
<a href="page1.html?b" target="_blank">B</a>

在page1.html

中

 var parts = window.location.search.substr(1);
 alert('Link '+parts+' was pressed');

Answer 3

以上答案可能是另一种选择。我宁愿建议使用document.referrer来识别它。 有关更多详细信息，请参阅堆栈溢出查询： How do you get the previous url in Javascript?

Answer 4

您可以通过onclick事件

进行内联

Select model, price, rating, state, brands.brandname, brands.website, 
bikebrandsellstock.size, bikebrandsellstock.brandstock, bikeshopsellbike.bikeshopname, bikeshopsellbike.size, bikeshopsellbike.bikeshopstock 
from bikes 
INNER JOIN brands ON bikes.model = brands.model 
INNER JOIN bikebrandsellstock ON bikes.model = bikebrandsellstock.model 
INNER JOIN bikeshopsellbike ON bikes.model = bikeshopsellbike.model 
WHERE SUM(bikebrandsellstock.stock+bikeshopsellbike.stock) 
IN (SELECT MAX(SUM(bikebrandsellstock.stock+bikeshopsellbike.stock)))
