使用Javascript / Jquery在按钮单击时更改div中的文本

[英]Using Javascript / Jquery to change text in div upon button click

here is the array 这是阵列

var copyText= [
'this is the first line',
'Simply put, the second line',
'impressed by the third line.'
    ];

These don't work ... 这些不起作用......

$("#thisbutton").click(function () {
$("#thetext").innerHTML("meow meow");
});

or 要么

$("#thisbutton").click(function () {
$("#thetext").innerHTML(copyText[1]);
});

or 要么

$("#thisbutton").click(function () {
$("#thetext").text(copyText[1]);
});


$("#thisbutton").click(function () {
$("#thetext").html(copyText[1]);
});

What I am missing? 我错过了什么? thks. THKS。

First of all, innerHTML is a native DOMElement property, not a jQuery method. 首先, innerHTML是本机DOMElement属性,而不是jQuery方法。 jQuery 's html method is the equivalent. jQueryhtml方法是等价的。

Secondly, you are not wrapping this in a ready handler: 其次,你没有将它包装在一个ready处理程序中:

Try this: 试试这个:

$(function() {
  var copyText= [
   'this is the first line',
   'Simply put, the second line',
   'impressed by the third line.'
  ];
  $("#thisbutton").click(function () {
     $("#thetext").text(copyText[1]);
  });

});

    $(function () {
        $("#thisbutton").click(function () { $("#thetext").html("meow meow"); });
    });

</html>

If you want to replace the complete div try replaceWith() jquery function 如果要替换完整的div,请尝试使用replaceWith()jquery函数

 $("#thetext").replaceWith("htmldata");
