Shazron Abdullah updated CB-9435:
---------------------------------
Description:
In https://github.com/litehelpers/Cordova-sqlite-storage/issues/147 someone
reported that my sqlite plugin could not handle \u2028 characters on iOS, and
further testing on my part isolated this to the result callback message. I made
a version of cordova-ext-echo at
https://github.com/brodybits/cordova-ext-echo-and-length that can be used to
demonstrate this issue cordova-ios.
If I install the plugin from
https://github.com/brodybits/cordova-ext-echo-and-length and run the following
code on the iOS version:
{code}
var Echo = cordova.require('org.apache.cordova.plugins.echo.Echo');
Echo.echo('first\u2027second', function(v) {
console.log('cb 1: ' + v);
});
Echo.echo('third\u2028fourth', function(v) {
console.log('cb 2: ' + v);
});
Echo.echo('fifth\u2029six', function(v) {
console.log('cb 3: ' + v);
});
Echo.len('first\u2027second', function(v) {
console.log('len cb 1: ' + v);
});
Echo.len('third\u2028fourth', function(v) {
console.log('len cb 2: ' + v);
});
Echo.len('fifth\u2029six', function(v) {
console.log('len cb 3: ' + v);
});
{code}
I get the following result:
{code}
2015-07-31 01:21:11.968 cijt[25760:18e03] cb 1: first‧second
2015-07-31 01:21:11.971 cijt[25760:18e03] len cb 1: 12
2015-07-31 01:21:11.973 cijt[25760:18e03] len cb 2: 12
2015-07-31 01:21:11.973 cijt[25760:18e03] len cb 3: 9
{code}
We can see that we can send a string with U+2028 and U+2029 from Javascript to
Objective-C with no problems: if Objective-C calculates and returns the length
it works but if Objective-C tries to send the same string back to Javascript it
fails.
I discovered the following article that seems to describe the cause:
http://timelessrepo.com/json-isnt-a-javascript-subset (Cordova does seem to
handle the \u000A and \u000D characters OK.)
When I ran the same test program on Android (with the same plugin installed), I
get all of the callbacks ok (trace filtered by hand):
{code}
