jQuery
Hi,
I am using jquery with json. My client pages generate json, which I store on my server. The clients can then fetch the json back out later, parse, and show it.
Since my clients are generating the json, it may not be safe. I think jquery uses eval() internally. Is that true? Is there a way to use the native json parsers from the browsers where available, otherwise fall back to manual parsing if not? I'm new to jquery so I don't know where I'd insert my own parsing code. I'm doing something like:
$.ajax({
url: 'myservlet',
type: 'GET',
dataType: 'json',
timeout: 1000,
error: function(){
alert('Error loading JSON');
},
success: function(json){
alert("It worked!: " + json.name + ", " + json.grade);
}
});
so in the success() method, the json object is already parsed for me. Is there a way to catch it as a raw string first? Then I can decide whether to use the native parsers or manual parsing (hoping there's a jquery plugin for that..).
The articles I'm reading are all from different years, so I don't know if jquery has already abandoned eval() already for json,
Thank you
