问题描述
我正在通过ID获取CSS选择器.调用getCSS方法为
I am getting CSS selector by ID. I get an error when I call the getCSS method as
UpdateActualPath actualPath= new UpdateActualPath();
actualPath.getCSS("https://www.google.co.in/", "a");
这是我的代码:
import java.io.IOException;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class UpdateActualPath {
static UpdateActualPath updateObject = new UpdateActualPath();
static WebDriver driver = new FirefoxDriver();
public void getCSS(String url, String tagname) throws IOException {
// driver.get("http://scripting.jdpoweronline.com/mrIWeb/mrIWeb.dll?I.Project=T1_QTYPE&i.test=1");
driver.get("file:///home/himansu/Desktop/Static.html#4"); // url
String jQuerySelector = "'body'";
JavascriptExecutor executor = (JavascriptExecutor) driver;
String strJavaScript = (String) executor.executeScript("return $(" + jQuerySelector + ").html()");
Document docparse = Jsoup.parse(strJavaScript);
Elements inputTags = docparse.select("a"); // tagname
if (!inputTags.isEmpty()) {
Element tempTag = null;
for (Element inputTag : inputTags) {
String tempString = "";
tempTag = inputTag;
while (tempTag.tagName() != "html") {
String tagId = "";
String tagClass = "";
String tagType = "";
String tagLink = "";
if (tempTag.id() != "") {
tagId = "#" + tempTag.id() + " ";
tempString = tempTag.tagName() + tagId + tempString;
break;
}
else {
System.out.println("This Type Tag is Not Present in Current Web Page.....!!!!");
}
}
}
}
}
private String findHrefAtttribute(Element tempTag, Elements tags) {
String tlink = tempTag.attr("href");
String css = "[href='" + tlink + "']";
if (updateObject.checkType(tlink, tags) == 1)
return css;
else
return "";
}
public String findChekboxAtttribute(Element tag, Elements tags) {
String tagname = tag.attr("name");
String css = "[name='" + tagname + "']";
if (updateObject.checkType(tagname, tags) == 1)
return css;
else
return "";
}
public String findImageAtttribute(Element tag, Elements tags) {
String tagalt = tag.attr("alt");
String tagname = tag.attr("name");
if (updateObject.checkType(tagname, tags) == 1) {
String css = "[alt='" + tagalt + "']" + "[name='" + tagname + "']";
return css;
} else {
String css = "[alt='" + tagalt + "']";
return css;
}
}
public int checkType(String tagname, Elements chektags) {
int count = 0;
for (Element matchInputTag : chektags) {
String matchtaghreftype = matchInputTag.attr("href");
String matchtagtype = matchInputTag.attr("name");
if (matchtagtype.compareTo(tagname) == 0)
count++;
if (matchtaghreftype.compareTo(tagname) == 0) {
count++;
}
}
return count;
}
}
完整错误是:

当我将URL更改为 http://stackoverflow.com 时，它工作正常.
When I change the URL to http://stackoverflow.com it works fine.
推荐答案
您描述的问题与正在加载的页面上不存在jQuery一致.通过将getCSS中的第一个executeScript调用更改为:
The problem you describe is consistent with jQuery not being present on the page you are loading. You can avoid jQuery altogether by changing your first executeScript call in getCSS to:
String strJavaScript =
(String) executor.executeScript("return document.body.innerHTML");
它可用于Stack Overflow，因为Stack Overflow会加载jQuery.
It works on Stack Overflow because Stack Overflow loads jQuery.
