当插入符位于输入末尾的输入内时,在 contenteditable 中输入后立即移动插入符
Move caret right after input in contenteditable when caret is inside the input at the end of it
我遇到了这个问题。我在 contenteditable div 中插入输入元素。插入符号位于最后一个位置的输入中。我想要一些帮助如何通过执行某些功能在该输入之后立即移动光标。您会在我的代码中看到,我必须单击 (justInserted.click()
) 才能调整大小。如果我删除 justInserted.focus()
那么插入符号总是在 contenteditable 的开头。我希望有一个函数可以发现插入符位于 contenteditable 的特定输入中,当我调用它时,它会将插入符放在该特定输入之后。感谢您的帮助:)
我在插入符处插入的内容如下所示:
this.insertNodeAtCursor = function(node) {
var sel, range, html;
function containerIsEditable(selection) {
return $(selection.anchorNode).parent().hasClass("editable");
}
if (window.getSelection) {
sel = window.getSelection();
// only if it is a caret otherwise it inserts
// anywhere!
if (containerIsEditable(sel) && sel.getRangeAt
&& sel.rangeCount) {
var previousPosition = sel.getRangeAt(0).startOffset;
sel.getRangeAt(0).insertNode(node);
}
}
else if (document.selection
&& document.selection.createRange) {
range = document.selection.createRange();
html = (node.nodeType == 3) ? node.data
: node.outerHTML;
range.pasteHTML(html);
}
};
添加输入的函数是这样的:
this.addInput = function(suggestEntry, query) {
var id = suggestEntry.id;
var nodeClass = suggestEntry.nodeClass;
var uuid = suggestEntry.uuid;
var clause = null;
if (nodeClass === "Entity"){
clause = new Entity();
clause.uuid = uuid;
clause.id = id;
clause.text = suggestEntry.text;
}
var input = clause.toEditorElementHtml();
this.insertNodeAtCursor(input);
var rand = Math.floor((Math.random() * 1000000) + 1);
input.setAttribute('id', "rand-" + rand);
$rootScope.$broadcast("remove:query",query);
var autoSizingInputs = $('input[autosize="autosize"]');
var justInserted = $('#rand-' + rand);
$compile(autoSizingInputs)($scope);
justInserted.focus();
justInserted.click(); // a bit hacky :/
$(justInserted).val($(justInserted).val() + "");
};
这是一个片段,其中包含一个功能,可以在焦点输入之后立即移动插入符号。我已经在 Chrome 版本 47.0.2526.111 m、Firefox 43.0.4 和 IE 11 中对其进行了测试。
function setCaretAfterFocusedInput(container) {
var input = container.querySelector('input:focus');
if (input) {
container.focus(); // required for firefox
setCaretAfter(input);
}
}
function setCaretAfter(element) {
if (window.getSelection) {
var range = document.createRange();
range.setStartAfter(element);
var selection = window.getSelection();
selection.removeAllRanges();
selection.addRange(range);
}
}
// for demonstration purposes
document.addEventListener('keyup', function(e) {
if (e.which === 16) { // on SHIFT
var container = document.querySelector('div[contenteditable]');
setCaretAfterFocusedInput(container);
}
});
<p>When an input is focused, press shift to move the caret right after the input.</p>
<div contenteditable>
<input type="text" value="input1"><input type="text" value="no whitespace before this">
