Find xml attribute values with javascript(使用 javascript 查找 xml 属性值)
问题描述
如何使用 Javascript/jQuery 获取 XML 节点的属性值?
How do I get the attribute value of an XML node with Javascript / jQuery?
我正在尝试获取节点上duration属性的值,然后获取fixedValue.
I'm trying to get the value of the duration attribute on the node, then get the 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,我得到了:
So far I've got:
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);
};
第二个 console.log 打印 undefined.
The second console.log prints undefined.
推荐答案
我遇到的第一个问题是 currLoadXml 不是字符串.它需要用单引号括起来.
The first problem I ran into is that currLoadXml is not a string. It needs to be wrapped inside single quotes.
试试下面的方法
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);
}
});
};
