我有一个句子被定义为一个列表(一个字符串?一个数组? - 我不确定正确的术语)我想按顺序返回按任何键。我试图使用.split。这是列表和功能:
var list1 = "This is a test".replace(/\s/g, "\xA0").split("")
function transformTypedChar(charStr) {
var position = $("#verse1").text().length;
if (position >= list1.length) return '';
else return list1[position];
}
目前," T"从列表的开头重复返回,并忽略列表的其余部分。我按如下方式调用该函数:
document.getElementById("verse1").onkeypress = function(evt) {
var val = this.value;
evt = evt || window.event;
// Ensure we only handle printable keys, excluding enter and space
var charCode = typeof evt.which == "number" ? evt.which : evt.keyCode;
if (charCode && charCode > 32) {
var keyChar = String.fromCharCode(charCode);
// Transform typed character
var mappedChar = transformTypedChar(keyChar);
var start, end;
if (typeof this.selectionStart == "number" && typeof this.selectionEnd ==
"number") {
// Non-IE browsers and IE 9
start = this.selectionStart;
end = this.selectionEnd;
this.value = val.slice(0, start) + mappedChar + val.slice(end);
// Move the caret
this.selectionStart = this.selectionEnd = start + 1;
} else if (document.selection && document.selection.createRange) {
// For IE up to version 8
var selectionRange = document.selection.createRange();
var textInputRange = this.createTextRange();
var precedingRange = this.createTextRange();
var bookmark = selectionRange.getBookmark();
textInputRange.moveToBookmark(bookmark);
precedingRange.setEndPoint("EndToStart", textInputRange);
start = precedingRange.text.length;
end = start + selectionRange.text.length;
this.value = val.slice(0, start) + mappedChar + val.slice(end);
start++;
// Move the caret
textInputRange = this.createTextRange();
textInputRange.collapse(true);
textInputRange.move("character", start - (this.value.slice(0,
start).split("\r\n").length - 1));
textInputRange.select();
}
return false;
}
};
如何按顺序返回整个列表?换句话说,在第一个关键事件中," T"在第二个关键事件中出现" h"出现等等。我可以在contenteditable div中实现这一点,但我使用输入类型:文本字段,因为我想在它们之间进行自动调整。
