Question

我目前正在利用 j和 Java文开展一个项目。将在OMS内有多个<代码>a要素,这些要素可使用rel属性,例如jqgal[mygal1]。

Once one of the anchors is clicked, I want to extract the value between the squared brackets, and read it into a variable for use later in the script. So for example in the following markup:

<a href=“my_image_1.jpg” rel=“jqgal[mygal1]”><img src=“some_image.jpg”/></a>

常规压缩应退还<条码>mygal1。我一直在试图说明这一点,迄今为止,已经取得了很多进展(这是其中之一)。是否有任何人表示采取这一行动的正确定期表述? 如果它有所帮助,则在方括号外加插始终为<编码>jqgal[。

Answer 1

这样做有助于:

$( a[rel^="jqgal"] ).click(function () {
    var val = $(this).attr("rel").match(/jqgal[(.*)]/)[1];
    // Do what you need with the  val 
});

Answer 2

Use /^.*?[(.*?)]/ regex on your rel attribute. The content of the group 1 (captured by the first parenthesis group) should be what you want.

var data = /^.*?[(.*?)]$/.exec(link.rel)[0];

Answer 3

var str = "jqgal[mygal1]"
var re = /[([^]]+)]/
console.log( str.match(re) );

解释性格

[       find a [ character - the  character escapes the [ so it matches the text
(        capture group start
[^]]+   match any character that is not a ]
)        capture group end
]       match a closing [ (not needed)

Answer 4

使用这一条码:<代码>/jqgal[(*)]/

它将在<条码>jqgal[]内搜寻任何座标。

例:

"jqgal[mygal1]".match(/jqgal[(.*)]/)
> ["jqgal[mygal1]", "mygal1"]
