正则提取两个字符串之间的内容的问题

Question

需处理的如下内容
{dede:pagestyle maxwidth='800' pagepicnum='12' ddmaxwidth='200' row='3' col='4' value='3'/}{dede:img ddimg='/uploads/allimg/110219/1-110219142110-lp.jpg' text='333' width='150' height='150'} /uploads/allimg/110219/1-110219142110.jpg {/dede:img}{dede:img ddimg='/uploads/allimg/110219/1-110219142111-lp.jpg' text='44' width='150' height='150'} /uploads/allimg/110219/1-110219142111.jpg {/dede:img}处理后要得到如下代码

Answer 4

郁闷放到dedecms的模板里 居然不能运行，我就是想用dedecms的sql标签把图集里的图片读取出来，太麻烦了

Answer 5

哦，你试试下面单独匹配图片地址的看看，不一定行。
<script>
var Str = "{dede:pagestyle maxwidth='800' pagepicnum='12' ddmaxwidth='200' row='3' col='4' value='3'/}{dede:img ddimg='/uploads/allimg/110219/1-110219142110-lp.jpg' text='333' width='150' height='150'} /uploads/allimg/110219/1-110219142110.jpg {/dede:img}{dede:img ddimg='/uploads/allimg/110219/1-110219142111-lp.jpg' text='44' width='150' height='150'} /uploads/allimg/110219/1-110219142111.jpg {/dede:img}";
var str = "";
Str.replace(/([\w*\/]{1,}[^\/]+jpg)[\S\s]*?([\w*\/]{1,}[^\/]+jpg)/gi, function($1,$2,$3) {
    str += '<a href="' + $3 + '" target="_blank"><img src="' + $2 + '"/></a>';
});
alert(str)
</script>

Answer 6

Character postion 752, 'img' Error！出来的是这个是什么意思

Answer 7

只显示前5幅：

Answer 8

是说你代码的第752个位置的字符 'img'错误，与正则表达式无关，因为匹配模式里面唯一的标识符只用了“jpg”，使用firebug调试定下位就知道怎么回事了。或许是因为前面帖子的字符串显示出来出现了断点。
还是封装下变量的好：
<script>
var Str = "{dede:pagestyle maxwidth='800' pagepicnum='12' ddmaxwidth='200' row='3' col='4' value='3'/}{dede:img ddimg='/uploads/allimg/110219/1-110219142110-lp.jpg' text='333' width='150' height='150'} /uploads/allimg/110219/1-110219142110.jpg {/dede:img}{dede:img ddimg='/uploads/allimg/110219/1-110219142111-lp.jpg' text='44' width='150' height='150'} /uploads/allimg/110219/1-110219142111.jpg {/dede:img} {/dede:img}{dede:img ddimg='/uploads/allimg/110219/1-110219142111-lp.jpg' text='44' width='150' height='150'} /uploads/allimg/110219/1-110219142111.jpg {/dede:img} {/dede:img}{dede:img ddimg='/uploads/allimg/110219/1-110219142111-lp.jpg' text='44' width='150' height='150'} /uploads/allimg/110219/1-110219142111.jpg {/dede:img} {/dede:img}{dede:img ddimg='/uploads/allimg/110219/1-110219142111-lp.jpg' text='44' width='150' height='150'} /uploads/allimg/110219/1-110219142111.jpg {/dede:img} {/dede:img}{dede:img ddimg='/uploads/allimg/110219/1-110219142111-lp.jpg' text='44' width='150' height='150'} /uploads/allimg/110219/1-110219142111.jpg {/dede:img} {/dede:img}{dede:img ddimg='/uploads/allimg/110219/1-110219142111-lp.jpg' text='44' width='150' height='150'} /uploads/allimg/110219/1-110219142111.jpg {/dede:img} {/dede:img}{dede:img ddimg='/uploads/allimg/110219/1-110219142111-lp.jpg' text='44' width='150' height='150'} /uploads/allimg/110219/1-110219142111.jpg {/dede:img} {/dede:img}{dede:img ddimg='/uploads/allimg/110219/1-110219142111-lp.jpg' text='44' width='150' height='150'} /uploads/allimg/110219/1-110219142111.jpg {/dede:img} {/dede:img}{dede:img ddimg='/uploads/allimg/110219/1-110219142111-lp.jpg' text='44' width='150' height='150'} /uploads/allimg/110219/1-110219142111.jpg {/dede:img} {/dede:img}{dede:img ddimg='/uploads/allimg/110219/1-110219142111-lp.jpg' text='44' width='150' height='150'} /uploads/allimg/110219/1-110219142111.jpg {/dede:img} {/dede:img}{dede:img ddimg='/uploads/allimg/110219/1-110219142111-lp.jpg' text='44' width='150' height='150'} /uploads/allimg/110219/1-110219142111.jpg {/dede:img}";String.prototype.getImage = function(num) {

Answer 9

似乎放到dedecms里还是不行，哪位朋友有dede的可以试下 放到他的模板下面看看能否运行，先谢谢楼上几位了

Answer 10

我把dede这样的字符改为de1de后 居然就可以，另外图片里可能有其他格式的图片，哪位给一个调用前5张，的代码，另外还要先把dede替换为de1de。大家帮帮忙，完了就结贴。

Answer 11

前5张一个很基本for循环计数
var str = "{dede:pagestyle maxwidth='800' pagepicnum='12' ddmaxwidth='200' row='3' col='4' value='3'/}{dede:img ddimg='/uploads/allimg/110219/1-110219142110-lp.jpg' text='333' width='150' height='150'} /uploads/allimg/110219/1-110219142110.jpg {/dede:img}{dede:img ddimg='/uploads/allimg/110219/1-110219142111-lp.jpg' text='44' width='150' height='150'} /uploads/allimg/110219/1-110219142111.jpg {/dede:img}";

BTW：“dede”是dedecms的关键保留词？给你替换了，是否管用不得而知，这与正则本身没有任何关系。

Answer 13

好像还是因为dede 这个要怎么解决啊
