setSelectionRange 适用于输入字段,但如何将光标放在可内容编辑字段的末尾?
setSelectionRange works with input fields, but how can I place the cursor at the end of a contenteditable field?
我之前问过为什么 setSelectionRange 不起作用,答案是因为它只适用于输入字段。但我想尝试使用 contenteditable 属性开发电子表格类型的页面。
window.onkeydown = function(e) {
if (e.keyCode === 113) {
setFocus()
}
}
function setFocus() {
element = document.getElementById('test')
element.focus() // works
.setSelectionRange(3,3) // Doesn't work
}
<div id="test" contenteditable>testing</div>
<p>Click in the Result window and then press F2.</p>
如何在用户按下 F2 后将光标置于字段末尾?
这可能是适合您的解决方案:
window.onkeydown = function(e) {
if (e.keyCode === 113) {
setFocus()
}
}
function setFocus() {
element = document.getElementById('test')
element.focus() // works
setCaretPosition(element,1); // Also works
}
function setCaretPosition(el, pos) {
el.focus();
var range = document.createRange();
var sel = window.getSelection();
range.setStart(el, pos);
range.collapse(true);
sel.removeAllRanges();
sel.addRange(range);
}
<div id="test" contenteditable>testing</div>
<p>Click in the Result window and then press F2.</p>
