如何在jQuery中替换字符串中的特定字符

Question

我在jQuery中有字符串，如：

<select id='orderlist-0' name='orderitems[0].orderitem.OrderItemId'></select>
<span class='field-validation-valid' 
      data-valmsg-for='orderitems[0].orderitem.OrderItemId' 
      data-valmsg-replace='true'></span>

现在我想用1替换[]中的所有0。哪种方法简单有效？

Answer 1

试试这个

var s="your string here"
    var result=s.replace(/0/g, '1');

Answer 2

您可以使用正则表达式来搜索和替换字符串。

var str,
    re;

str = "<select id='orderlist-0' name='orderitems[0].orderitem.OrderItemId'></select><span class='field-validation-valid' data-valmsg-for='orderitems[0].orderitem.OrderItemId' data-valmsg-replace='true'></span>";

re = /(\[)(0)(\])/g;

str = str.replace(re, '$11$3');
