JQuery parseXML和打印

Question

var usrconf = "<root><node>abc</node><node>efg</node></root>";
var xmlDoc = $.parseXML( usrconf );
$(xmlDoc).find('node').each(function(i) {
    // change node values here
});

现在，我如何打印更改后的XML？

Answer 1

$(this)使您可以访问在each()中选择的元素。i是如下所述的函数索引：http://api.jquery.com/each/

.each( function(index, Element) )

所以正确的代码是：

var usrconf = "<root><node>abc</node><node>efg</node></root>";
var xmlDoc = $.parseXML( usrconf );
$(xmlDoc).find('node').each(function(i) {
 $(this).attr('changed', true);
});
console.log(xmlDoc);

​，或者如果您想要序列化它。

var usrconf = "<root><node>abc</node><node>efg</node></root>";
var xmlDoc = $.parseXML( usrconf );
$(xmlDoc).find('node').each(function(i) {
 $(this).attr('changed', true);
});

console.log(xmlDoc);

// from http://stackoverflow.com/a/6507766/141200
function xmlToString(xmlData) { 

    var xmlString;
    //IE
    if (window.ActiveXObject){
        xmlString = xmlData.xml;
    }
    // code for Mozilla, Firefox, Opera, etc.
    else{
        xmlString = (new XMLSerializer()).serializeToString(xmlData);
    }
    return xmlString;
}   

console.log(xmlToString(xmlDoc));
