如果我們需要取得所有title裡的內容該如何做呢？
正規表示式後面加g表示多次符合
方式一：match
傳回陣列
方式二
##exec實例如下：
<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>
