Below, the editor will bring you an article on js to determine the function implementation method of two strings with the largest substrings. The editor thinks it is quite good, so I will share it with you now and give you a reference. Let's take a look with the editor

As shown below:

<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<script type="text/javascript">
function search(str1,str2)
{
var i=j=k=a=jk=kk=0;
var m=;
var n=;
var index=0;
var maxlen=0;
var str="";
var flag=0;
for (i=0;i<n;i++)
{
k=i;
for (j=0;j<m;j++)
{
a = 0;
flag = 0;
jk=j;
kk=k;
while(jk<=m&&str1[kk]==str2[jk])
{
kk++;jk++;a++;
flag = 1;
}
if(flag==1)
{
if(a>maxlen)
{
maxlen = a;
index = jk-a;//The first item of matching}
} 
}

}
for(;maxlen>0;maxlen--)
{
str+=str2[index++];

} 
return str;
}
alert(search("kssd","ssdfa"));
</script>
<body>
<div>11</div>
</body>
</html>

The above is the entire content of the function implementation method for determining the largest substring of two strings brought to you by the editor. I hope everyone supports me~
