var regJs = ""；
var resdata = "
<style>
#slyderAdv {
height: 100%; background: #f02e38;
}
</style>
<div class="tmp-editable" id="slyderAdv"
</div>
<script>
document.getElementById("slyderAdv").onmouseleave = function(){
document.getElementById("cancelcolor").style.display = "none"
}
</script>";
resdata.replace(/<script.*?>([\s\S]+?)<\/script>/img,function(_,js){ //正则匹配出script中的内容
regJs = js
});
这时得到的regJs 就是script标签里阿扁的内容
