When using Twitter's Bootstrap, how can I change a popover's content?
提问by brentmc79
I'm using the popover feature from Twitter's Bootstrap js. I have a button that, when clicked, executes this javascript:
我正在使用 Twitter 的 Bootstrap js 中的 popover 功能。我有一个按钮，点击后会执行这个 javascript：
$("#popover_anchor").popover({trigger: "manual",
placement: "below",
offset: 10,
html: true,
title: function(){return "TITLE";},
content: function(){return "CONTENT TEXT";}});
$("#popover_anchor").popover("show");
There's also another button that executes basically the same javascript, except that the title and content functions return different text.
除了标题和内容函数返回不同的文本外，还有另一个按钮执行基本相同的 javascript。
Note that they both define the popover on the same element, just with different content.
请注意，它们都在同一个元素上定义了弹出框，只是内容不同。
The problem is, once either button is clicked and the js is executed, no subsequent clicks from the other button will change the popover content. So once the popover is initialized, how can I update/change the content?
问题是，一旦单击任一按钮并执行 js，其他按钮的后续单击都不会更改弹出窗口的内容。因此，一旦初始化弹出框，我该如何更新/更改内容？

the purpose of the titleattribute is to accept a value of type functionwhich provides this very functionality.
该title属性的目的是接受function提供此功能的类型值。
for example: if you set your title to:
例如：如果您将标题设置为：
title: function() { return randomTxt(); }
and you have,
你有，
function randomTxt()
{
arr = ['blah blah', 'meh', 'another one'];
return arr[Math.floor(Math.random() * 4)];
}
you will keep getting a different title for your popover. It is upto you to change the logic of randomTextto fetch a title dynamically.
您将继续为您的弹出框获得不同的标题。您可以更改randomText动态获取标题的逻辑。

You can do that by accessing popover instance data directly as explained here:

您可以通过直接访问 popover 实例数据来做到这一点，如下所述：https:

This example is taken from the lnked page:
此示例取自 lnked 页面：
var myPopover = $('#element').data('popover')
myPopover.options.someOption = 'foo'

Here is the solution I said right there:
这是我在那里说的解决方案：
Bootstrap popover content cannot changed dynamically
var popover = $('#exemple').data('bs.popover');
popover.options.content = "YOUR NEW TEXT";
popover is an object if you want to know more about it, try to do console.log(popover) after you define it to see how you can use it after !
popover 是一个对象，如果您想了解更多信息，请尝试在定义它之后执行 console.log(popover) 以查看之后如何使用它！
