D3 how to select element by ID when there is a dot in ID

Question

I have

<text id="element.id.with.dots" x="10" xml:space="preserve" y="10" stroke="none">

How can I select it using d3.select? This doesn't seem to work, it returns null

var textElem = d3.select("text[id=element\\.id\\.with\\.dots]");

and this :

var textElem = d3.select("text[id=element.id.with.dots]");

gives me error in Firebug console window:

SyntaxError: An invalid or illegal string was specified

Answer 1

Use a quoted string to delimit the value of your attribute:

var textElem = d3.select("text[id='element.id.with.dots']");

var el = d3.select("text[id='element.id.with.dots']");
el.style({fill: 'red'})
