Autodesk Forge如何从名称中获取双价

Question

I have an extension which loads a docking panel with a text field and a button. The functionality of this button would be to display the DB-ID of the item name given in the text field.

Something like: Rubber = 2130

where Rubber is the input and 2130(db-id) will be the output

How can I achieve this?

Thanks in advance.

Answer 1

Would suggest using .search() method, which is a supported way:

viewer.search('Rubber', function(dbIds){
  // here the dbIds is a list of dbIds, you can handle it
  callback(dbIds); // handle the results async
}, function(error){
  // handle errors here...
}, ['name'] /* this array indicates the filter: search only on 'Name'*/
)

And look here on how to improve performance on search.

There is no such API available currently, but a workaround can be used in this case. It's shown as the following:

//-- For the element type or element category like "Floor [" or "Floor"

var it = viewer.model.getData().instanceTree;
var strIdx = it.nodeAccess.strings.indexOf( "Floor [" );
// var strIdx = it.nodeAccess.strings.indexOf( "Floor" );
var nameIdx = it.nodeAccess.names.indexOf( strIdx );
for( var key in it.nodeAccess.dbIdToIndex ) {
  if( it.nodeAccess.dbIdToIndex[key] === nameIdx ) console.log( key )
}


//-- For element name like "Floor[766598]":
var it = viewer.model.getData().instanceTree;
var eidIndex = it.nodeAccess.nameSuffixes.indexOf( 766598 );
for( let key in it.nodeAccess.dbIdToIndex ) { 
  if( it.nodeAccess.dbIdToIndex[key] === eidIndex ) console.log( key ) 
}

PS Since this is just a workaround, not the formal solution. You would have to use it at your own risk.

If you want to avoid using the search() method, you could also create your own Object that maps the name to ID's. This is a temporary workaround until Autodesk implements its own method.

var instanceTree = viewer.model.getData().instanceTree; // Get model tree
var allDbIds = Object.keys(instanceTree.nodeAccess.names); //get array of all ID's
var forgeNameMap = {} //Empty array for mapping names
allDbIds.map(function(id) { 
    forgeNameMap[instanceTree.getNodeName(id)] = id
})

let rubberID = forgeNameMap["Rubber"]
