Beware that indexOf is not supported by earlier versions of IE. In which case the following code can be included. 

<pre><code>if(!Array.indexOf){
 Array.prototype.indexOf = function(obj){
 for(var i=0; i&lt;this.length; i++){
 if(this[i]==obj){
 return i;
 }
 }
 return -1;
 }
 }

I don't know exactly what you are looking for, but it seems from your code that you want to find a first name. If this was just an example, and you don't want a first name, I probably won't be answering your question well. I couldn't find anything about <code>if(foo ^= bar)</code> online.

It would be easy to get the first word in a string (like a first name) through <code>var firstName = name.split(' ')[0]</code>.

To find out how similar a string is to another string, <a href="http://andrew.hedges.name/experiments/levenshtein/" rel="nofollow noreferrer">this</a> was suggested in another <a href="https://stackoverflow.com/questions/5042873/javascript-text-similarity-algorithm/5042897#5042897">SO answer</a>. I don't know anything about it.

Personally if given the task of finding if a first name is similar to a string given, I would compare similarity of both strings after <code>string.toLowerCase()</code>, and/or compare each character. The library above seems much better if you are looking for overall similarity, but a custom function would allow much more control over similarity detection.

<pre><code>function checkSimilarity(str, target, tolerance) {
 for(x=0; x &lt; str.length();x++) {
 if(str.split('')[x].toLowerCase() == target.split('')[x].toLowerCase()) {
 similar += 1;
 }
 }
 if(similar =&gt; (target.length() * tolerance)) {
 return true;
 }
 else {
 return false;
 }
}
</code></pre>

No clue how the function above works, but it's what I thought of. (Tolerance needs to be between <code>0</code> and <code>1</code>)

I have an array and would like to use the same concept as a like in SQL to find certain characters in a string.

This what I'm trying to use:

<pre><code>if (nameArray[i].nameInfo.fullName ^= "Bob") {
 // TODO: some code.
}
</code></pre>

Thanks for any help.

我有一个数组，并希望使用与SQL中的like相同的概念来查找字符串中的某些字符。这就是我想要使用的：if (nameArray[i].nameInfo.fullName ^= "Bob") {   // TODO: some code.}谢谢你的帮助。
