How to properly use parseInt to select/check a span element from within a chrome extension

Question

I am attempting to use parseInt to determine if a span element is equal to or greater than 1 from within my Google Chrome Extension.

I am attempting to check for this "0" to change and on change to launch a specific URL - See Image for Reference

Here is a screenshot of the "inspect" option from within chrome.

Here is the page HTML:

<div id="onlinebar" style="text-align: right">

	<a href="javascript:win1()" class="tb_options" title="Kalbėkis su savo piratais.">Užsuk į smuklę</a>&nbsp;&nbsp;| &nbsp;&nbsp;

	<span id="tb_gang" class="tb_options" onClick="ShowTbPopup(this); obShowHide(0)">My Fleet: (<b>2</b>)</span>&nbsp;&nbsp;| &nbsp;&nbsp;

	<span id="tb_friend" class="tb_options" onClick="ShowTbPopup(this); obShowHide(1)">My Friends: (<b>2</b>)</span>&nbsp;&nbsp;| &nbsp;&nbsp;

	<span id="tb_enemies" class="tb_options" onClick="ShowTbPopup(this); obShowHide(2)">My Enemies: (<b>0</b>)</span>&nbsp;&nbsp;&nbsp;&nbsp;

	<a id="closebox" href="#" onclick="javascript:var conf = confirm('Are you sure you want to remove the login box? (It can be turned back on from settings)'); if(conf){ document.getElementById('onlinebar').style.display='none'; setBarPrefs('11769'); }" style="margin-right:20px;"><img src="/images/close.gif" border="0"/></a>

</div>

This is what I have tried:

function checkEnemies(){
	numEnemies = parseInt($$("[id^=tb_enemies]")[0].title.split(" ")[0]);
	if (numEnemies >= 1){
		$$("a[href*='sea']")[0].click();
		return true;
	}
	return false;
}


var bool = checkEnemies();

And also this:

function checkEnemies(){
	numEnemies = parseInt($$('#tb_enemies')[0].title.split(" ")[0]);
	if (numMessages >= 1){
		$$("a[href*='sea']")[0].click();
		return true;
	}
	return false;
}


var bool = checkEnemies();

Thanks for any help you can offer.

The number doesn't seem to be set as the value of the title attribute, you can get it directly from the element's content, here is an example:

// jQuery

let number = parseInt($("#tb_enemies b").text());
console.log("jQuery the number is:", number);

// vanilla JavaScript

number = parseInt(document.querySelector("#tb_enemies b").textContent);
console.log("vanilla JavaScript the number is:", number);

<div id="onlinebar" style="text-align: right">

	<a href="javascript:win1()" class="tb_options" title="Kalbėkis su savo piratais.">Užsuk į smuklę</a>&nbsp;&nbsp;| &nbsp;&nbsp;

	<span id="tb_gang" class="tb_options" onClick="ShowTbPopup(this); obShowHide(0)">My Fleet: (<b>2</b>)</span>&nbsp;&nbsp;| &nbsp;&nbsp;

	<span id="tb_friend" class="tb_options" onClick="ShowTbPopup(this); obShowHide(1)">My Friends: (<b>2</b>)</span>&nbsp;&nbsp;| &nbsp;&nbsp;

	<span id="tb_enemies" class="tb_options" onClick="ShowTbPopup(this); obShowHide(2)">My Enemies: (<b>0</b>)</span>&nbsp;&nbsp;&nbsp;&nbsp;

	<a id="closebox" href="#" onclick="javascript:var conf = confirm('Are you sure you want to remove the login box? (It can be turned back on from settings)'); if(conf){ document.getElementById('onlinebar').style.display='none'; setBarPrefs('11769'); }" style="margin-right:20px;"><img src="/images/close.gif" border="0"/></a>

</div>

What this does is to get the text content of the first <b> element inside the element with ID tb_enemies and parse that text to an integer.
