如何在用户单击按钮时将文本添加到textarea [英] How to add text to textarea when user clicks a button
问题描述
我想在用户点击按钮时将文本添加到textarea。我知道如何连接字符串并将其添加到textarea,但是我想要的是将文本添加到textarea内的位置/位置,用户在其中单击,然后添加文本
预先致谢
这里是来自我的参考资料:
< script>
函数input(){
var text =这里是您要输入的文本。;
document.forms.form1.area.value = text;
}
< / script>
< form name ='form1'>
点击< input onclick ='input()'type ='button'value ='BUTTON'id ='button'>< br>
< textarea name ='area'>< / textarea>
< / form>
表示一个示例,显示当一个按钮被点击时,一行文本添加到textarea中。
为什么我在其中添加了javascript?因为html属性只是不足以让它成为它。
可能会有帮助:D

var text = "here the text that you want to input.";
document.forms.form1.area.value = text;
}
</script>
<form name='form1'>
Click<input onclick='input()' type='button' value='BUTTON' id='button'><br>
<textarea name='area'></textarea>
</form>
