Question

I am generating JavaScript pages through Java code like:

FileOutputStream fs=new FileOutputStream("C:\\Documents and Settings\\prajakta\\Desktop\\searcheng.html");
OutputStreamWriter out=new OutputStreamWriter(fs);
out.write("<script language='JavaScript' type='text/javascript'>");
out.write("var str=new String('C:\\Documents and  Settings\\prajakta\\Desktop\\substr.html');");
out.write("var beg=str.lastIndexOf('\\');");//double' \' **Problem Stmt**

And so on.

The problem is when searcheng.html is created it contains

var beg=str.lastIndexOf('\');//single '/'

which creates a problem in finding index of ‘\’.
How should I write this problem so that it will contain double “\”?

Similarly how should I write a statement

out.write("document.write('< a href='str'> '+str.slice(beg+1,end)+' </a>');"); 

so that it will create statement in JavaScript as

document.write('< a href=" 'str' ">  '+str.slice(beg+1,end)+'  </a>');

and the link will go to page whose address is stored in str?

Answer 1

out.write("var beg=str.lastIndexOf('\\\\');");

should do the trick. Double for Java, double again for JavaScript…
