Jquery 按属性部分值查找元素

Question

我有以下元素

<li data-attr="sessionContext='test session'"></li>
<li data-attr="sessionContext='test session 12345'"></li>

// I want to get all elements with [data-attr=someContext*=] -doesn't 
matter someContext= value, but doesn't work
$("[data-attr]") // gets all elements, but not sessionContext only
$("[data-attr='sessionContext=test session']") // works but for single element only

Answer 1

使用选择器，你可以试试这个：

$('[data-attr="sessionContext=test session"]')     
// will return the element sessionContext=test session

$('[data-attr^="sessionContext=test session"]' )   
// will return all that begin with sessionContext=test session

$('[data-attr$="sessionContext=test session"]' )   
// will return all that end with sessionContext=test session

$('[data-attr*="sessionContext=test session"]' )   
// will return all that contain sessionContext=test session

Answer 2

试试这个：

$("[data-attr^=sessionContext]")

^ 将匹配以 sessionContext 开头的任何内容
