Quick question about json objects and jquery

JavaScript
1

Hey,

If I do this

var agentInfoBar = {
        toggleAgentInfo: $(".toggle-agent-info"),
        agentInfo: $(".agent-info")
    }

and then make several subsequent references to

agentInfoBar.agentInfo

will I gain the benefit of only making one call to jquery to retrieve that element set?

Absolutely. This is a good thing to do.

Just be aware that if you later change the dom in a way that would make that selector return a different set of elements, the jquery object you hold a reference to will not be automatically updated.

Right, cool thanks, I’ll need to ensure I update any references if they change. Thanks!
