Javascript 使用正则表达式替换
<input type="text" value="[tabelas][something][oas]" id="allInput">
<script type="text/javascript">
allInput = document.getElementById('allInput');
var nivel = new Array('tabelas', 'produto');
for (var i =0; i < nivel.length ; i++ )
{
alert(" oi => " + allInput.value + " <-- " + nivel[i]) ;
var re = new RegExp("^\[" + nivel[i] + "\]\[.+\].+", "g");
alert(re);
allInput.value = allInput.value.replace(
re, "OLA");
alert(" oi 2 => " + allInput.value + " <-- " + nivel[i]) ;
}
</script>

"\["将生成字符串[," \\["将产生\[。\[.+\]与[abc][def]等字符串匹配。您可能需要\[\w+\]或类似的东西。"\["will result in the string[,"\\["will result in\[.\[.+\]matches strings like[abc][def]. You probably want\[\w+\]or something similar.如果您使用
new RegExp(...)语法构造 RegExp，则需要两个 反斜杠来转义字符。If you construct a RegExp from the
new RegExp(...)syntax, then you need two backslashes to escape a character.
