How to screen double quotes

[yur15t]

I'm trying to use quoted text in one of node's attributes:

var network_json = {
dataSchema: {
nodes: [ { name: "label", type: "string" },
{ name: "foo", type: "string" }
]
},
data: {
nodes: [ { id: "1", label: "1", foo: "Text without quotes" },
{ id: "2", label: "2", foo: "Some \"quoted\" text" }
]
}
};
vis.draw({network: network_json});

And then making listeners for each node:

vis.addListener("click", "nodes", function(event) {
alert(event.target);
})

But I've got "Unexpected token ILLEGAL" error while clicking on a node
with quoted text. How should I screen quotes there?

Why don't you try single-quoted strings?

Example:

foo: 'Some "quoted" text'

Some JSON parsers seem to have issues with special characters. We've added some workarounds to CW in order to avoid those issues, but sometimes it seems that a new browser version comes up with another parser problem.

Can you please tell us what browser/version you are using?

Thanks,

Hi, Christian, thanks for your response.

That was just an example of where i'm using quoted strings. Actually i
receive JSON object via jQuery.getJSON() from PHP-script. It contains
list of names and descriptions as strings. Both can contain single or
double quotes.

$.getJSON(scriptURL+'?t=q&q='+escape(q), function(data){
var nodes_arr = new Array();
var edges_arr = new Array();

for (var i=0;i<data.length;i++)
{
nodes_arr[nodes_arr.length] = {id: data[i].name,
label: data[i].name,
abstract: data[i].abstract,
};
}

drawNodes(nodes_arr);
})

Here is a JSON-string from PHP-script:
[{"name":"some name","abstract":"some text"},{"name":"some other
name","abstract":"some \"quoted\" text"}]

And here is how i draw nodes:

function drawNodes(n_arr)
{
var net = {

dataSchema: {
nodes: [
{name: "label", type: "string" },

{name: "abstract", type: "string" },
]
},
data:{
nodes:n_arr,
}
};

vis.draw({network: net});
vis.ready(function() {

vis.addListener("click", "nodes", function(event)
{
alert(event.target);
}

});
}

I even tried data[i].abstract.split('\"').join('"'), didn't help.

This bug appears in every browser i tried: Chrome 18.0; Firefox 11.0,
Opera 11.61, IE 8.0

I've created a bug report for it (http://cbio.mskcc.org/cytoscape/bugs/view.php?id=2690) and have already found a solution, but need to run more tests before releasing the fixed version.

Thanks for the feedback!

Thanks for bugreporting that!
.split('\"').join('\\"') doesn't help either though.

It has to be fixed in the Flash code.

Hey Christian,

I facing issues/errors while using double quotes or single quotes in attribute values string,
with Vis.networkModel().data.nodes.length

So the bug stated above was fixed?

Thanks

Hi Ekansh, 

It should have been fixed a long time ago. Are you using the latest version of C.Web (1.0.2)?

If so, can you tell me the versions of your OS, browser and Flash player, since I can't reproduce it? If possible, please also send a sample of your original network data (json, xgmml, etc).

Thanks,

Christian
