按钮修改文本区域中的文本,然后复制修改后的文本
Button to modify text in the text area and then copy modified text
这是我的代码,但无法正常工作。
btn.addEventListener("click", function () {
var get = document.getElementById('myTxtArea').value
var res = get.split(/[ ,-]+/).join(';')
textarea.innerText = res
res.select();
document.execCommand('copy');
})

看来你把事情复杂化了,超出了他们需要的范围。试试这个:
function copy() {
let textarea = document.getElementById("textarea");
textarea.select();
document.execCommand("copy");
}
或
function myFunction() {
/* Get the text field */
var copyText = document.getElementById("myInput");
/* Select the text field */
copyText.select();
copyText.setSelectionRange(0, 99999); /* For mobile devices */
/* Copy the text inside the text field */
document.execCommand("copy");
/* Alert the copied text */
alert("Copied the text: " + copyText.value);
}
这个有效:
<textarea id="textarea">my value</textarea><br>
<button id="myButton" onclick="btnClick()">My Button</button>
//with jQuery
$(()=>{
$("#myButton").click(()=>{
let txtArea = $("#textarea");
let txtVal = txtArea.val();
// do something
txtVal += " my added value";
txtArea.val(txtVal);
document.getElementById("textarea").select();
});
});
//OR without jQuery
function btnClick() {
let txtValue = document.getElementById("textarea").value;
//do something
txtValue += " add new value";
document.getElementById("textarea").value = txtValue;
document.getElementById("textarea").select();
}
