仿百度搜索框智能提示功能，在搜索关键字变色的功能里，输入数字会有问题
仿百度搜索框智能提示功能，在搜索关键字变色的功能里，输入数字会有问题，如果数组中含有（1）数字，当文本框第一次按下1这个数字来搜索时，会出现问题,例如：数组中有2123，在文本框输入1，结果会显示2123[[[1]]]；如果数组中有两条或以上含有（1）数字的，则搜索结果第一行会这样显示，之后的都正常显示。输入“，”时也有问题，会出现一个标签字符串，原因是因为都“，”来分割的。
贴上我的搜索关键字变色的代码，大家给我看一下吧。
//搜索结果关键字高亮显示
function setHeightKeyWord(id, keyword, color, bold) {
if (keyword == "")
return;
var tempHTML = $("#" + id).html();
var htmlReg = new RegExp("\<.*?\>", "i");
var arrA = new Array();
for (var i = 0; true; i++) {
var m = htmlReg.exec(tempHTML);
if (m) {
arrA[i] = m;
}
else {
break;
}
tempHTML = tempHTML.replace(m, "[[[[" + i + "]]]]");
}
var replaceText
if (bold)
replaceText = "<b style='color:" + color + ";'>$1</b>";
else
replaceText = "<font style='color:" + color + ";'>$1</font>";
var arrayWord = keyword.split(',');
for (var w = 0; w < arrayWord.length; w++) {
var r = new RegExp("(" + arrayWord[w].replace(/[(){}.+*?^$|\\\[\]]/g, "\\$&") + ")", "ig");
tempHTML = tempHTML.replace(r, replaceText);
}
for (var i = 0; i < arrA.length; i++) {
tempHTML = tempHTML.replace("[[[[" + i + "]]]]", arrA[i]);
}
$("#" + id).html(tempHTML);
}
你代码就有问题，输入1，替换的html时for (var i = 0; true; i++) { var m = htmlReg.exec(tempHTML);不就出现了 [[[[1]]]]这个，做关键字替换的时候你[[[[这个里面的1也被替换了
所以你的tempHTML = tempHTML.replace("[[[[" + i + "]]]]", arrA[i]);肯定就不匹配了
你遍历子对象进行替换就好了，干嘛要替换html标签
<ul id="ul">
<li>12313</li>
<li>12313</li>
<li>233</li>
<li>12313</li></ul>

setHeightKeyWord('ul', '1', 'blue');

replaceText = "<b style='color:" + color + ";'>$1</b>";
else
replaceText = "<font style='color:" + color + ";'>$1</font>";
var arrayWord = keyword.split(',');
var nodes = $('#' + id + '>li');//注意修改子对象选择器
for (var w = 0; w < arrayWord.length; w++) {
for (var i = 0; i < nodes.length; i++) {
var r = new RegExp("(" + arrayWord[w].replace(/[(){}.+*?^$|\\\[\]]/g, "\\$&") + ")", "ig");
nodes[i].innerHTML = nodes[i].innerHTML.replace(r, replaceText);
}
}
