How to click svg using querySelector?

I am trying to build a chrome extension to click an SVG on a webpage using the below command but it shows that "click" is not a function.
Can anyone give me some direction in order to solve this issue?
document.querySelector("div[class^='SubmitChat__SubmitButton']").querySelector("svg > path(0)").click();
<form class="SubmitChat__SubmitChatWrapper-kLTVjd ezNulO">
<div id="PinToTop" style="display: none; border: groove; margin: 5px; padding: 5px;"></div>
<div class="DefaultComments__DefaultCommentsWrapper-drohEF dbvkCO">
<div class="SubmitChat__TextAreaWrapperBox-ijaLYA uQa-DJ">
<textarea data-track-category="Interaction_Comment" data-track-action="click" data-track-name="field_comment" class="SubmitChat__TextAreaWrapper-cEDMAF joGtiU" style="height: 44px;"></textarea>
</div>
<div class="SubmitChat__SubmitButton-kXYuum kSQpDq">
<span class="isvg loaded SubmitChat__SendMessageIcon-hzVurU lcJXRC">

</form>

You can't really click an svg path but here is a solution:
const pathElem = document.querySelector("div[class^='SubmitChat__SubmitButton'] svg > path")
pathElem.onclick = () => console.log("clicked")
pathElem.dispatchEvent(new Event("click"))
pathElem.dispatchEvent(new Event("click"))
<form class="SubmitChat__SubmitChatWrapper-kLTVjd ezNulO">
<div id="PinToTop" style="display: none; border: groove; margin: 5px; padding: 5px;"></div>
<div class="DefaultComments__DefaultCommentsWrapper-drohEF dbvkCO">
<div class="SubmitChat__TextAreaWrapperBox-ijaLYA uQa-DJ">
<textarea data-track-category="Interaction_Comment" data-track-action="click" data-track-name="field_comment" class="SubmitChat__TextAreaWrapper-cEDMAF joGtiU" style="height: 44px;"></textarea>
</div>
<div class="SubmitChat__SubmitButton-kXYuum kSQpDq">
<span class="isvg loaded SubmitChat__SendMessageIcon-hzVurU lcJXRC">
<svg xmlns="http://www.w3.org/2000/svg" width="32" height="32" viewBox="0 0 32 32">

</path>
</svg>
</span>
</div>
</div>
</form>
Note that .click() works with HTML but not SVG elements. MDN
Also note that the click event handler in your case is probably not listening on the path element but rather on the svg, div or span tag.

how to let the svg image completely move inside the div tag only?

I can move my svg image(animated character) in any direction but I want to restrict the movement inside play area div tag only and also it's not using all the area of the play area div tag to move properly.Here's a gif for the reference
<div class="playarea">
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" id="gokusvg" >
<image id="goku" height="140" width="150" xlink:href="images/goku.png" transform="">
</image>
</image>
</svg>
.playarea {
grid-area: playarea;
border:2px solid black;
height:400px;
width:400px;
}
/* image svg */
#gokusvg {
height:400px;
width:400px;
}
Google Blockly javascript file
//block definition for Up arrow block
Blockly.Blocks['up'] = {
init: function() {
this.appendDummyInput()
.setAlign(Blockly.ALIGN_CENTRE)
.appendField(new Blockly.FieldImage(
"images/up.svg",
50,
50,"*",Up));
this.setColour("#FFFFFF");
}
};
/*character movement funtions*/
//moves the character in upward/north direction
function Up() {
// TODO: Assemble JavaScript into code variable.
var code = document.getElementById('goku').style.y="-100";
var sound = new Audio("sounds/move.mp3"); // buffers automatically when created
sound.loop = false;
sound.play();
}

> Add bootstrap class and use raw and column span for stay image into div and
give % to playarea class instead of height and width in px.It will help you.

How to convert all elements inside html div element into an image using javascript without any third party library

I am having a div with 3 elements. I want to convert that whole div into an image without using third party tool. Kindly provide me any suggestion regarding this.
<!DOCTYPE html>
<html>
<body>
<div id="div1">DIV 1<br>
<svg width="50" height="50">
<path d="M0,0 L50,0 L50,50 Z"
style="stroke: #006666; fill:none;"/>
</svg>
<div>DIV 2</div>
<input type="button" value="Button"/>
</div>
</body>
</html>

This is probably a good starting point. I have slightly modified the answer from this question https://stackoverflow.com/a/27232525/8085668. I have just removed the callback and added a click event. Please refer to it for a detailed explanation of the code.
var svgText = document.getElementById("myViewer").outerHTML;
var myCanvas = document.getElementById("canvas");
var ctxt = myCanvas.getContext("2d");
var btn = document.getElementsByClassName('convert2Png')[0];
function drawInlineSVG(ctx, rawSVG) {
var svg = new Blob([rawSVG], {type:"image/svg+xml;charset=utf-8"}),
domURL = self.URL || self.webkitURL || self,
url = domURL.createObjectURL(svg),
img = new Image;
img.onload = function () {
ctx.drawImage(this, 0, 0);
domURL.revokeObjectURL(url);
};
img.src = url;
}
// usage:
btn.addEventListener('click', function() {
drawInlineSVG(ctxt, svgText);
});
<!DOCTYPE html>
<html>
<body>
<div id="div1">DIV 1<br>

Get image height and change the image container height to auto

I'm trying to determine the height of images in containers and if any image has a height of less than 300 pixels then I want its container height to be set to auto.
Here is my code:
<style>
.container {
width: 500px;
height: 500px;
}
</style>
<script>
var img = document.getElementsByTagName("img");
if (img.height < 300) {
var x = document.getElementsByClassName('container');
x.style.height="auto";
}
</script>
<div class="container">
<img height="500" width="500" src="/some_img.jpg"/>
</div>
<div class="container">
<img height="500" width="500" src="/some_img.jpg"/>
</div>
<div class="container">
<img height="500" width="500" src="/some_img.jpg"/>
</div>
<div class="container">
<img height="250" width="250" src="/some_img.jpg"/> // This image height is less than 300 pixels.
</div>
<div class="container">
<img height="500" width="500" src="/some_img.jpg"/>
</div>
Any help would be appreciated.

First you get all image tags, then itterate through them, if their height is less than 500, then you get its parent element and set its height to 'auto'
here is a working example
var img = document.getElementsByTagName("img");
console.log(img)
for (index in img){
if (img[index].height < 300) {
img[index].parentNode.style.height="auto";
}
}

img = getElementsByTagName("img") returns all images, not just one, so you can't use it as img.height, you should use for loop or jQuery selector
x = document.getElementsByClassName('container') also returns all elements, so you can't set its style directly. And you need to set style for parent element of current processed image, not just first or all of them. You can use jQuery .parent()
Your script is executed before the img elements begin to exist. Either put you script after html or use jQuery $(document).ready() event
I think you should put a dot before slash in src (src="./some_img.jpg")
So with jQuery it will look like this:
<script>
$(document).ready(function(){
$("img").each(function(){
if( $(this).height() < 300 ) {
$(this).parent().height( "auto" );
}
});
});
</script>

Vanilla JS
Iterate over the images. If they are <300 and their parent has the class of 'container' then set the parent's style.height to 'auto:
var imgs = document.getElementsByTagName("img");
for (i in imgs){
if (imgs[i].height < 300 && imgs[i].parentNode.className.indexOf('container') != -1) {
imgs[i].parentNode.style.height="auto";
}
}
var imgs = document.getElementsByTagName("img");
for (i in imgs){
if (imgs[i].height < 300 && imgs[i].parentNode.className.indexOf('container') != -1) {
imgs[i].parentNode.style.height="auto";
}
}
.container {
width: 500px;
height: 500px;
}
<div class="container">
<img height="500" width="500" src="http://www.placehold.it/500/500/"/>
</div>
<div class="container">
<img height="500" width="500" src="http://www.placehold.it/500/500/"/>
</div>
<div class="container">
<img height="500" width="500" src="http://www.placehold.it/500/500/" />
</div>
<div class="container">
<img height="250" width="250" src="http://www.placehold.it/250/250/"/><!--This image height is less than 300 pixels.-->
</div>
<div class="container">
<img height="500" width="500" src="http://www.placehold.it/500/500/"/>
</div>
jQuery
Use jQuery's filter() to simply find all .containers that contain images with a height < 300:
$(".container")
.filter(function(){return $(this).find("img").height() < 300;})
.css("height", "auto");
$(function(){
$(".container").filter(function(){return $(this).find("img").height() < 300;}).css("height", "auto");
});
.container {
width: 500px;
height: 500px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<img height="500" width="500" src="http://www.placehold.it/500/500/"/>
</div>
<div class="container">
<img height="500" width="500" src="http://www.placehold.it/500/500/"/>
</div>
<div class="container">
<img height="500" width="500" src="http://www.placehold.it/500/500/" />
</div>
<div class="container">
<img height="250" width="250" src="http://www.placehold.it/250/250/"/><!--This image height is less than 300 pixels.-->
</div>
<div class="container">
<img height="500" width="500" src="http://www.placehold.it/500/500/"/>

This has to do with a layering order. Your middle state is buried under the other two. To bring it to top so that the border shows up topmost, you have to insert the element last.
A quickfix would be to give your element an ID: <svg id="id_svg" ...
Then in your getstate() function, insert this at the end:
document.getElementById('id_svg').appendChild( elem );
A possibly better way to handle this set of complexities is to use a library such as raphaeljs. It fixes many annoyances, and is cross-browser compatible.
