代码如下:
var st="A[B]C[D]E[F]G";
var reg =/[w]/ig;
var s1 = st.replace(reg,"");
var s2=[];
var arr;
while((arr=reg.exec(st))!=null)s2.push(arr[0]);
alert(s1);
alert(s2.join(""));
FF下正确显示,IE下S2为空.
网上查不到资料,请各位指点一二.
查询过程中得了个意外收获
代码如下:
var st="A[B]C[D]E[F]G";
var reg =/[w]/ig;
var s1 = st.replace(reg,"");
var s2=[];
var arr;
while((arr=/[w]/ig.exec(st))!=null)s2.push(arr[0]);
alert(s1);
alert(s2.join(""));
该写法IE死循环RegExp的lastIndex没有得到更新
In some recent code, I'm using Javascript to parse through the result set of an AJAX call, which happens to be returning a full HTML page. Yes, ideally, I'd have an AJAX call return something usable like JSON, but in this case the PHP back-end code had to remain as is and the front-end adjust to handle the legacy HTML it returned.
I needed to grab a link (1 or more) from the returned HTML page so that I could immediately display those links in separate windows (each was a generated report). So, my first stab at this is shown in the following code example. Basically, we have setup a string to represent the returned HTML, in this case it contains 3 links; and we want to use the standard Javascript RegExp object's exec() method to grab the URLS (href parameter) for each of those links. In our example, we just print them out in an unordered list to see what we've captured. The important lines of code we'll be looking at are highlighted in the example below.
