Solutions to data loss due to special symbols in AJAX post data

When you use AJAX to transmit data, the server side loses data when it has a plus (+), connector (&), or percent sign (%) data. Analyze the format of AJAX-transmitted data and JavaScript syntax:

1. "+" number: javascript resolves to a string connector, so "+" will lose the variable space when the server receives the data.

2. "&": javascript resolves to a variable connector, so when the server side receives the data, the data after the & symbol is lost.

The workaround is to replace the code with a regular expression (assuming that poststr is a string of data that you want to transfer via AJAX)

Poststr = Poststr.replace (/%/g, "%25");  Poststr = Poststr.replace (/\&/g, "%26");  Poststr = Poststr.replace (/\+/g, "%2b");
