如何告诉 Ajax.ActionLink OnSuccess 回调哪个元素启动了 ajax
How to tell Ajax.ActionLink OnSuccess callback which element initiated the ajax
问:
我希望我的剃须刀视图看起来像这样
@Ajax.ActionLink("A", "Buy", new AjaxOptions() { HttpMethod = "Post", OnSuccess = "updateLetter" }, new { id = "letter-A" })
@Ajax.ActionLink("B", "Buy", new AjaxOptions() { HttpMethod = "Post", OnSuccess = "updateLetter" }, new { id = "letter-B" })
@Ajax.ActionLink("C", "Buy", new AjaxOptions() { HttpMethod = "Post", OnSuccess = "updateLetter" }, new { id = "letter-C" })
我的 javascript 看起来像这样
function updateLetter(letter)
{
$("#letter-" + letter).toggleClass('selected');
}
这个想法是,如果我单击 A 链接,它将执行 ajax 并在该元素上切换类。不过,我不确定如何连接它。我错过了什么?

首先修复你的重载,因为你的重载不会编译。Ajax.ActionLink
要传递参数,您可以这样做:
@Ajax.ActionLink(
"A",
"About",
null,
new AjaxOptions {
HttpMethod = "POST",
OnSuccess = "updateLetter('A')"
},
new {
id = "letter_A"
}
)
然后:
function updateLetter(letter)
{
$("#letter-" + letter).toggleClass('selected');
}
就我个人而言,我不喜欢帮手。我使用另一种方法,它由标准 HTML 组成:Ajax.*
ActionLink
@Html.ActionLink(
"A",
"About",
null,
new {
@class = "letter"
id = "letter_A"
}
)
我悄悄地将 AJAXify 放在一个单独的 javascript 文件中:
$(function() {
$('.letter').click(function() {
var $letter = $(this);
$.post(this.href, function(result) {
$letter.toggleClass('selected');
});
});
});
下一个:在何处包含不显眼的验证脚本
