javascript - Get index of current object in array? Pass current object to a function. Angular JS -


i trying call function object in array. (the objects of array placed on map.) function should evaluate 'status' object has, , return url icon based on status. have pass current object function.. how do it?

my array of objects:

mvc.models = [{   id: "1",   icon: evaluatecolor(currentobject),   status: 'green' }, {   id: "2",   icon: evaluatecolor(currentobject),   status: 'red' }];

my function:

function evaluatecolor(currentobject) {   if (currentobject.status === 'green') {     return 'images/green_marker.png'   }   else if (currentobject.status === 'yellow') {     return 'images/yellow_marker.png'   }   else {     return 'images/red_marker.png'   } }

i have tried pass object function passing 'this', object logs undefined. because 'this' refers controller , not object.

mvc.models = [{   id: "1",   icon: evaluatecolor(this),   status: 'green' }, {   id: "2",   icon: evaluatecolor(this),   status: 'red' }];

and if wants see html: (the objects houses should shown on angular google maps)

<ui-gmap-markers         models='mvc.models'         coords="'coords'"         icon="'icon'"         > </ui-gmap-markers>

can point me in right direction? thanks!

you don't need pass whole object evaluatecolor. modify to

function evaluatecolor(status) {   if (status === 'green') {     return 'images/green_marker.png'   }   else if (status === 'yellow') {     return 'images/yellow_marker.png'   }   else {     return 'images/red_marker.png'   } }

and call evaluatecolor('green'/'yellow') , anyways have color available while initializing object. this.status not work object declaration still not complete.

alternatively, can call initialize models without icon attribute , call function:

for(var in models){    models[i].icon = evaluatecolor(models[i].status); }

hope solves query.. :)

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
