搜索xml文件以查找搜索字符串中的任何匹配项
当searchterm是关键字之一（例如'driver'或'white）时，它会给出结果并且似乎没问题，但是当searchterm扩展到'driver 102'或'R-22 red'时，没有任何反应。
（使用RegEx表达式，转义空格，尝试在searchterm上循环 - 它遍历每个字母）
关于如何从searchterm中的多个单词获得结果的任何想法？（例如'driver 102'或'R-22 red'）
*xml doc:*
<searchable_index>
<Search>
<title>driver</title>
<keyword>101 101</keyword>
<link>R-12</link>
<color>white</color>
<itemid>test</itemid>
</Search>
<Search>
<title>driver</title>
<keyword>102</keyword>
<link>R-22</link>
<color>red</color>
<itemid>1test</itemid>
</Search>
</searchable_index>
*Javascript:*
function loadIndex() {
if (document.implementation && document.implementation.createDocument) {
xmlDoc = document.implementation.createDocument("", "", null);
xmlDoc.load("index9.xml");
}
else if (window.ActiveXObject) {
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xmlDoc.load("index9.xml");
}
}
function searchIndex() {
if (!xmlDoc) {
loadIndex();
}
var searchterm = document.getElementById("searchme").value;
searchtermconvert=searchterm.toString();
var arrsearch=xmlDoc.getElementsByTagName("Search");
results = new Array;
if (searchtermconvert.length < 3) {
alert("Enter at least three characters");
} else {
for (var i=0;i<arrsearch.length;i++){
var variable = arrsearch[i].textContent;
var exp = new RegExp(searchtermconvert,"gi");
if ( variable.match(exp) != null) {
results.push(arrsearch[i]);
}
}
showResults(results,searchtermconvert);
}
}
2 个答案:
答案 0 :(得分：0)
提供多个搜索词的搜索结果的其他部分：
var exp = new RegExp(res[0],"i");
var exp2 = new RegExp(res[1],"i");
var exp3 = new RegExp(res[2],"i");
var exp4 =new RegExp(res[3],"i");
var exp5= new RegExp(res[4],"i");
然后为if语句添加额外条件
if ( variable.match(exp) != null && variable.match(exp2) != null && variable.match(exp3) != null && variable.match(exp4) != null && variable.match(exp5) != null)
结果是您可以搜索多个搜索词。
