I write a form that inserts some xml tags into textarea. I use this function:
(function ($) {
addCustomTag = function (name, param, value) {
var code = "<" + name + " " + param + "=\"" + value + "\">\n</" + name + ">";
document.getElementById("codeArea").value += code;
};
})(jQuery);
How can I make that some other function will insert subtags into tags that were created before? XML code will never be used on server. All I need is to insert tex in specific line which is depends on what was on this line before not cutting it. Something like this:
addCustomSubtag = function(name,param,value,parent) {
document.getElementById("codeArea").selectionStart = document.getElementById("codeArea").value - parent.length;
var code = "<" + name + " " + param + "=\"" + value + "\">\n</" + name + ">";
document.getElementById("codeArea").value += code;
};
Javascript isn't necessary. It also can be written on jQuery. Thanks.
这可能会很有用: http : //dwieeb.github.com/jquery-textrange/
You can any of these jQuery functions
Update:
Actually we can use jQuery DOM manipulation methods to manipulate XML also.
var xml = "<main/>";
alert(xml); // <main/>
var $xml = $(xml).append($("<sub1/>"));
alert($xml.html()); // <sub1></sub1>
$xml.find("sub1").append($("<sub2/>"));
alert($xml.html()); // <sub1><sub2></sub2></sub1>
alert($xml.get(0).outerHTML); // <main><sub1><sub2></sub2></sub1></main>
