[英]how to extract a value of variable from a javascript function in the html page while parsing an html page
我必须解析一个html页面。 我必须在分配给javascript函数的以下html中提取name元素的值。 我如何使用JSoup做到这一点。
<input type="hidden" name="fields.DEPTID.value"/>
JS:
departmentId.onChange = function(value) {
var departmentId = dijit.byId("departmentId");
if (value == null || value == "") {
document.transferForm.elements["fields.DEPTID.value"].value = "";
document.transferForm.elements["fields.DEPTID_DESC.value"].value = "";
} else {
document.transferForm.elements["fields.DEPTID.value"].value = value;
document.transferForm.elements["fields.DEPTID_DESC.value"].value = departmentId.getDisplayedValue();
var locationID = departmentId.store.getValue(departmentId.item, "loctID");
var locationDesc = departmentId.store.getValue(departmentId.item, "loct");
locationComboBox = dijit.byId("locationId");
if (locationComboBox != null) {
if (locationID != "") {
setLocationComboBox(locationID, locationDesc);
} else {
setLocationComboBox("AMFL", "AMFL - AMY FLORIDA");
}
}
}
};
我会尽力教您顶峰:
//Connect to the url, and get its source html
Document doc = Jsoup.connect("url").get();
//Get ALL the elements in the page that meet the query
//you passed as parameter.
//I'm querying for all the script tags that have the
//name attribute inside it
Elements elems = doc.select("script[name]");
//That Elements variable is a collection of
//Element. So now, you'll loop through it, and
//get all the stuff you're looking for
for (Element elem : elems) {
String name = elem.attr("name");
//Now you have the name attribute
//Use it to whatever you need.
}
