从文本区域获取文本统计信息。
哪个会更好?
这个?
function getStats() {
var text = textarea.value,
stats = {};
stats.chars = text.length;
stats.words = text.split(/\S+/g).length - 1;
stats.lines = text.replace(/[^\n]/g, "").length + 1;
return stats.lines + " lines, " + stats.words + " words, " + stats.chars + " chars";
}
还是这个?
function getStats() {
var text = textarea.value,
chars = text.length,
words = text.split(/\S+/g).length - 1,
lines = text.replace(/[^\n]/g, "").length + 1;
return lines + " lines, " + words + " words, " + chars + " chars";
}
