如果我们需要获取所有title里的内容该如何做呢?
正则表达式后面加g表示多次匹配
方式一:match
返回数组
方式二
exec
实例如下:
<script> var str='<a href="//www.aliexpress.com/store/product/OOOT-BAORJCT-174296-22mm-10yard-lot-cartoon-Ribbons-Thermal-transfer-Printed-grosgrain-Wedding-Accessories-DIY-handmade/2349150_32810795709.html" rel="external nofollow" rel="external nofollow" title="OOOT BAORJCT 174296 22mm 10yard/lot cartoon Ribbons Thermal transfer Printed grosgrain Wedding Accessories DIY handmade material">OOOT BAORJCT 174296 22mm 10yard/lot cartoon Ribbons...</a><a href="//www.aliexpress.com/store/product/OOOT-BAORJCT-174296-22mm-10yard-lot-cartoon-Ribbons-Thermal-transfer-Printed-grosgrain-Wedding-Accessories-DIY-handmade/2349150_32810795709.html" rel="external nofollow" rel="external nofollow" title="999OOOT BAORJCT 174296 22mm 10yard/lot cartoon Ribbons Thermal transfer Printed grosgrain Wedding Accessories DIY handmade material">OOOT BAORJCT 174296 22mm 10yard/lot cartoon Ribbons...</a>'; var reg=/title="(.*?)">/g; var res = str.match(reg); console.log(str.match(reg)); while( res = reg.exec(str)) { console.log(res[1]); } </script>
效果如下:
