function Insert(str) {
var obj = document.getElementById('content');
if(document.selection) {
obj.focus();
var sel=document.selection.createRange();
document.selection.empty();
sel.text = str;
} else {
var prefix, main, suffix;
prefix = obj.value.substring(0, obj.selectionStart);
main = obj.value.substring(obj.selectionStart, obj.selectionEnd);
suffix = obj.value.substring(obj.selectionEnd);
obj.value = prefix + str + suffix;
}
obj.focus();
}
然后在后台调用这个方法进行添加。追问.net 有没有相关的方法呀
