找到JavaScript的XML属性值(Find xml attribute values with

我如何使用Javascript / jQuery的XML节点的属性值？

我试图让节点上的时间属性的值，然后得到fixedValue。

<loanAmount>
    <interestRates>
        <interestRate allowInterestOnly="true" type="variable" value="5.82"/>
        <interestRate allowFixed="true" allowInterestOnly="true" duration="1" fixedInterestOnlyValue="5.7" fixedValue="5.7" variableInterestOnlyValue="5.82"/>
        <interestRate allowFixed="true" allowInterestOnly="true" duration="3" fixedInterestOnlyValue="5.75" fixedValue="5.75" variableInterestOnlyValue="5.82"/>
        <interestRate allowFixed="true" allowInterestOnly="true" duration="5" fixedInterestOnlyValue="6.64" fixedValue="6.56" variableInterestOnlyValue="5.82"/>
        <interestRate allowFixed="true" allowInterestOnly="true" duration="10" variableInterestOnlyValue="5.82"/>
    </interestRates>
</loanAmount>'

到目前为止，我有：

var currentLoanRates = function() {
    var currLoanXml = '<loanAmount><interestRates><interestRate allowInterestOnly="true" type="variable" value="5.82"/><interestRate allowFixed="true" allowInterestOnly="true" duration="1" fixedInterestOnlyValue="5.7" fixedValue="5.7" variableInterestOnlyValue="5.82"/><interestRate allowFixed="true" allowInterestOnly="true" duration="3" fixedInterestOnlyValue="5.75" fixedValue="5.75" variableInterestOnlyValue="5.82"/><interestRate allowFixed="true" allowInterestOnly="true" duration="5" fixedInterestOnlyValue="6.64" fixedValue="6.56" variableInterestOnlyValue="5.82"/><interestRate allowFixed="true" allowInterestOnly="true" duration="10" variableInterestOnlyValue="5.82"/></interestRates></loanAmount>',
    xmlDoc = $.parseXML( currLoanXml ),
    $xml = $( xmlDoc ),
    $intRate = $xml.find("interestRate"),
    $varIntRate = $intRate.attr("fixedValue");

    console.log($intRate);
    console.log($varIntRate);
};

第二打印的console.log 不确定的 。

Answer 1:

我遇到的第一个问题是，currLoadXml不是字符串。 它需要单引号里面包裹。

尝试使用下面的方法

var currentLoanRates = function() {
    var currLoanXml = '<loanAmount><interestRates><interestRate allowInterestOnly="true" type="variable" value="5.82"/><interestRate allowFixed="true" allowInterestOnly="true" duration="1" fixedInterestOnlyValue="5.7" fixedValue="5.7" variableInterestOnlyValue="5.82"/><interestRate allowFixed="true" allowInterestOnly="true" duration="3" fixedInterestOnlyValue="5.75" fixedValue="5.75" variableInterestOnlyValue="5.82"/><interestRate allowFixed="true" allowInterestOnly="true" duration="5" fixedInterestOnlyValue="6.64" fixedValue="6.56" variableInterestOnlyValue="5.82"/><interestRate allowFixed="true" allowInterestOnly="true" duration="10" variableInterestOnlyValue="5.82"/></interestRates></loanAmount>',
    xmlDoc = $.parseXML( currLoanXml ),
    $xml = $( xmlDoc ),
    $intRate = $xml.find("interestRate");
    $intRate.each(function(index, element) { 
        if(element.attributes["duration"]) {
            console.log("Duration :" + element.attributes["duration"].value);
        }

        if(element.attributes["fixedValue"]) {
            console.log("Fixed value:" + element.attributes["fixedValue"].value);
        }
    });

};

Answer 2:

对于那些寻找出从外部文件加载XML，这可能会有所帮助：

<script>
    $.ajax({
        url: 'sample.xml',
        dataType: 'xml',
        success: function (data) {
            // Extract relevant data from XML
            var xml_node = $('loanAmount', data);
            $parameter = xml_node.find('interestRate');
            $parameter.each(function (index, element) {
                if (element.attributes["allowFixed"]) {
                    console.log("Allow Fixed : " + element.attributes["allowFixed"].value);
                }

                if (element.attributes["duration"]) {
                    console.log("Duration: " + element.attributes["duration"].value);
                }
            });
        },
        error: function (data) {
            console.log('Error loading XML data');
        }
    });
</script>
