For some reason clicking the button will not but the variable in the textbox, I'm not getting any syntax errors in my compiler so I think it's a logic error. THanks in advance
JS:

$('.teambtn').click(function() {
document.getElementById('team').text = (testvar);
});
html:
<textarea id=team cols="50" rows="10">
Your Team Will be here:
</textarea>
<button type="button" id=teambtn class="btn">Export</button>
推荐答案
（'.teambtn'）。click（function（）{
document.getElementById（'team'）。text =（testvar）;
}）;
html：
< textarea < span class =code-attribute> id = 团队 cols = 50 行 = 10 >
您的团队将在这里：
< / textarea >
< 按钮 type = 按钮 id = < span class =code-keyword> teambtn class = btn > 导出< / button >
('.teambtn').click(function() { document.getElementById('team').text = (testvar); }); html: <textarea id=team cols="50" rows="10"> Your Team Will be here: </textarea> <button type="button" id=teambtn class="btn">Export</button>
<pre><script>
document.getElementById('your id of textbox').value = your_variable_js;
</script></pre>
