我有这个代码/ jQuery插件。
jQuery.fn.extend({
insertAtCaret: function(myValue) {
return this.each(function(i) {
if (document.selection) {
//For browsers like Internet Explorer
this.focus();
sel = document.selection.createRange();
sel.text = myValue;
this.focus();
}
else if (this.selectionStart || this.selectionStart == '0') {
//For browsers like Firefox and Webkit based
var startPos = this.selectionStart;
var endPos = this.selectionEnd;
var scrollTop = this.scrollTop;
this.value = this.value.substring(0, startPos) + myValue + this.value.substring(endPos, this.value.length);
this.focus();
this.selectionStart = startPos + myValue.length;
this.selectionEnd = startPos + myValue.length;
this.scrollTop = scrollTop;
} else {
this.value += myValue;
this.focus();
}
})
}
});
此代码用于在插入符号处插入非默认字符。例如,有人按Tab键,它会插入\ t或者按下E按钮,它会插入一个P代替。我遇到的问题是这个代码在textarea中运行得很漂亮,但是当我尝试在contentEditable div上使用它时,没有任何反应。那么我可以修改此代码以使用contentEditable div吗?谢谢!
