Is it possible to target and manipulate just one of the coordinate numbers within an SVG path's 'd' attribute using JavaScript? For example, how can I access the number 0 in "L25 0" to increment it for animating the path?
function NavHalf() {
var arrow = document.getElementById("arrowUp");
arrow.setAttribute('d', 'M0 25 L25 0 L50 25');
}<svg height="25" width="50" onclick="NavHalf()">
<path id="arrowUp" d="M0 0 L25 25 L50 0 " style="stroke:green;stroke-width:2; fill:none" />
</svg>In a statement from Michaels, it was mentioned that there is no direct way in the DOM to access and modify individual points within a path definition.
The only option available is string manipulation.
function NavHalf(x,y) {
var arrow = document.getElementById("arrowUp");
arrow.setAttribute('d', 'M0 0 L' + x + ',' + y + ' L50 0');
}<button type="button" onclick="NavHalf(25,0)">Position 1</button>
<button type="button" onclick="NavHalf(20,15)">Position 2</button>
<button type="button" onclick="NavHalf(25,25)">Position 3</button>
<svg height="25" width="50">
<path id="arrowUp" d="M0 0 L25 25 L50 0" style="stroke:green;stroke-width:2; fill:none" />
