我有一个Buy
按钮,用户可以单击该按钮购买特定产品。
这会将他们带到我建立的购买表格中。
该表单上的一个字段使用URL参数,因此它知道用户要购买哪种产品。
所以我想做的是在页面的某个位置之前(Buy
按钮所在的位置)有一个HTML选择字段,并允许用户在那里选择产品。
然后,当他们单击Buy
按钮时,它将通过URL传递所选值。例如:
// Some content here promoting the three products.
// Now I want a select field for the user to choose one of the three products, like this.
<select id="productSelect">
<option value="product1">Product 1</option>
<option value="product2">Product 2</option>
<option value="product3">Product 3</option>
</select>
// Then I have some more content here showing the pros/cons of each product.
// Finally, I have a buy button at the bottom of the page that takes them to the page with the purchase form.
// Here is where I want to grab the value of the select field and pass it through via the "product" parameter like this.
<a class="button" href="/buy/?product='select value here'">Buy</a>

使用JavaScript执行此操作
document.getElementsByClassName("button")[0].addEventListener("click", function(event) {
var product = document.getElementById("productSelect").value;
event.target.setAttribute("href", "/buy?product=" + product);
});
这将起作用。
