Question

我有一个html表单，我需要在锚标记的title属性中添加换行符。我在网上找到了一些解决方案，但它们都没有在我的代码中运行。

我尝试添加
\n





<br>



不确定缺少什么。是因为数据切换阻止了打破title属性？

  $(document).ready(function () {
        $('form').attr('novalidate', true);
        $('[data-toggle="tooltip"]').tooltip(); 


<a class="helptext fa fa-question-circle" data-toggle="tooltip" title="Additional information -&#013; You can provide further information here to for your&#013; application to issue a new card.&#013; Ensure a maximum of 200 characters&#013; is entered – including spaces."></a>

Answer 1

popover是一个更好的解决方案，但可以在浏览器中实现此功能：

$(document).ready(function () {
	$('form').attr('novalidate', true);
	//$('[data-toggle="tooltip"]').tooltip(); 
	
	$('.helptext')[0].title = "I like\nlines"
        // you can also use $('.helptext').attr("title",decodeURI("I like%0A to%0Ause%0Alines"))
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a class="helptext fa fa-question-circle" data-toggle="tooltip" href="#" title="Additional information -&#013; You can provide further information here to for your&#013; application to issue a new card.&#013; Ensure a maximum of 200 characters&#013; is entered – including spaces.">test</a>

Answer 2

使用JavaScript设置标题对我有用。

document.getElementById('asdf').title = 'line1\nline2';

title属性中的新行字符在工具提示中不起作用
