You don't need jQuery, or Polymer for that, just do:
document.querySelector("button[name^='mybutton']")
Within a Polymer element we have a help for finding elements inside the
local dom: this.$(id) and this.$$(selector), which are roughly equivalent
to this.shadowRoot.querySelector('#id') and
this.shadowRoot.querySelectorAll(selector).
Since ids are useful again (because they're scoped to a shadow root), I'd
recommend using this pattern when you can:
<template>
<button id="mybutton">Click Me</button>
</template>
<script>
...
doSomething(this.$.mybutton);
</script>
Of course, Polymer also adds a bunch of helpers for declaratively adding
event listeners, data-binding to values, etc., so many times you might not
even need to get a reference in code.
