Question

我想检索在第三列中过滤出的所有行。我已经附上了网站参考结构的图片，这是实际的网站http://juliemr.github.io/protractor-demo/

    //I found this online, but its not working for me it still retrieve all the data from the table
    tablefil(){
        //third column id like to filter
       var name = "11";

        // This is like element.all(by.css(''))
        return $$("table[class='table']").filter(function(row) {
          // Get the second column's text.
          return row.$$("td[class='ng-binding']").get(3).getText().then(function(rowName) {
            // Filter rows matching the name you are looking for.
            return rowName === name;

          });
        }).getText().then(function(text){
            //Display rows that fits my filter above
           console.log('\n'+text+'\n')
        }) 
    }

您的代码中有两个问题：

1）不正确的CSS选择器无法找到表的所有行。正确的是：table[class='table'] tbody > tr

2）数组索引从“ 0”开始，因此获取第三列应使用 row.$$("td").get(2)

tablefil(result){

  return $$("table[class='table'] tbody > tr")

      .filter(function(row) {

        // find out which row's Result is equal to argument: result

        return row.$$("td").get(2).getText().then(function(text) {
          return !result || text.trim() === result;
        });

      })
      .each(function(row){

        // read the text of 2nd column: Expression on matched row

        row.$$("td").get(1).getText().then(function(text){
            console.log('expression: ' + text)
        });

        // or if you want to print the Expression and Result together
        row.$$("td:nth-child(2),td:nth-child(3)").getText().then(function(texts){
            console.log(texts[0], '=', text[1])
        });  
      })
}


tablefil() // will print all rows
tablefil('11') // will only print row's Result == 11

量角器检索带有过滤列的所有行
