Search Functions
The resourcesSearch function exposes the following functions:
define(function () {
/**
* Constructor. Takes context as argument.
* @param contextObj - map of properties.
*/
function ResourcesSearch(contextObj){};
/**
* Get/Set 'q' parameter of the query
* @param contextObj - map of properties.
* @returns this if 'value' sent to the method,
* otherwise returns current value of the parameter
*/
ResourcesSearch.prototype.q= function(value){};
/**
* Get/Set 'folderUri' parameter of the query
* @param value - new value, optional
* @returns this if 'value' sent to the method,
* otherwise returns current value of the parameter
*/
ResourcesSearch.prototype.folderUri= function(value){};
/**
* Get/Set 'type' parameter of the query
* @param value - new value, optional
* @returns this if 'value' sent to the method,
* otherwise returns current value of the parameter
*/
ResourcesSearch.prototype.type= function(value){};
/**
* Get/Set 'offset' parameter of the query
* @param value - new value, optional
* @returns this if 'value' sent to the method,
* otherwise returns current value of the parameter
*/
ResourcesSearch.prototype.offset= function(value){};
/**
* Get/Set 'limit' parameter of the query
* @param value - new value, optional
* @returns this if 'value' sent to the method,
* otherwise returns current value of the parameter
*/
ResourcesSearch.prototype.limit= function(value){};
/**
* Get/Set 'recursive' parameter of the query
* @param value - new value, optional
* @returns this if 'value' sent to the method,
* otherwise returns current value of the parameter
*/
ResourcesSearch.prototype.recursive= function(value){}; |
/**
* Get/Set 'sortBy' parameter of the query
* @param value - new value, optional
* @returns this if 'value' sent to the method,
* otherwise returns current value of the parameter
*/
ResourcesSearch.prototype.sortBy= function(value){};
/**
* Get/Set 'accessType' parameter of the query
* @param value - new value, optional
* @returns this if 'value' sent to the method,
* otherwise returns current value of the parameter
*/
ResourcesSearch.prototype.accessType= function(value){};
/**
* Get/Set 'showHiddenItems' parameter of the query
* @param value - new value, optional
* @returns this if 'value' sent to the method,
* otherwise returns current value of the parameter
*/
ResourcesSearch.prototype.showHiddenItems= function(value){};
/**
* Get/Set 'forceTotalCount' parameter of the query
* @param value - new value, optional
* @returns this if 'value' sent to the method,
* otherwise returns current value of the parameter
*/
ResourcesSearch.prototype.forceTotalCount= function(value){};
return ResourcesSearch;

Finding Resources
The following code example shows how to perform a search and store the results in a variable:
// Populate the repository list
JRSClient.resourcesSearch({
// server: serverUrl,
folderUri:"/public/Samples",
recursive:true,
types:["reportUnit", "dashboard"],
success:listRepository,
error:function (err)
{ alert(err); }
}); |
The next two examples show different ways of handling results after making a simple repository search in the Public folder.
new ResourcesSearch({
server:"http://localhost:8080/jasperserver-pro",
folderUri: "/public",
recursive: false
})).run(function(resourceLookups){
// results here
}); |
var search = v.resourcesSearch({
folderUri: "/public",
recursive: false,
success: function(repo) {
console.log(repo.data()); // resourceLookups
}
}); |
You can also specify the runImmediately:false parameter so that you can set up the search in the first call, and run it later in a separate call. In the following code sample, the first statement builds a query but makes no request to the server, and the second statement actually sends the request, which executes the query.
var query = v.resourcesSearch({
server:"http://localhost:8080/jasperserver-pro",
folderUri: "/public",
recursive: false,
runImmediately : false
}));
query.run().done(function(results){
}) |
Reusing a Search Instance
If you make multiple searches, for example in different folders, you can create a function to do that using the ResourcesSearch function.
var folderContentQuery = new ResourcesSearch({
server:"http://localhost:8080/jasperserver-pro",
recursive: false
}));
// call 1
folderContentQuery.folderUri("/uri1").run(doSomethingWithResultFunction);
...
// call 2 after some time
folderContentQuery.folderUri("/uri2").run(doSomethingWithResultFunction); |
Reusing Search Results
Code example:
var call = new ResourcesSearch({
server:"http://localhost:8080/jasperserver-pro",
folderUri: "/public",
recursive: false
})).run(function(resourceLookups){
// data() available here
});
// at this point call.data() will return null until the run callback is called.
call.data() === null // -> true
.....
// if some data was obtained earlier, it accessible via data()
var resourceLookups = call.data(); |
Discovering Available Types
You can write code to discover and display the types that can be searched and types of sorting that can be specified.
visualize({
auth: {
name: "jasperadmin",
password: "jasperadmin",
organization: "organization_1"
}
}, function (v) {
buildControl("Resources types", v.resourcesSearch.types);
buildControl("Resources search sort types", v.resourcesSearch.sortBy);
}); |
function buildControl(name, options) {
function buildOptions(options) {
var template = "<option>{value}</option>";
return options.reduce(function (memo, option) {
return memo + template.replace("{value}", option);
}, "")
}
console.log(options);
if (!options.length){
console.log(options);
}
var template = "<label>{label}</label><select>{options}</select><br>",
content = template.replace("{label}", name)
.replace("{options}", buildOptions(options));
$("#container").append($(content));
} |
