如何正确使用parseInt从chrome扩展程序中选择/检查span元素

2024-05-19 • 问答

我正在尝试使用parseInt从我的Google Chrome扩展程序中确定span元素是否等于或大于1。

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.

这是HTML页面：

<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>

这是我尝试过的：

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();

还有这个：

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();

感谢您提供的任何帮助。

// 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);
