Question

我是jquery的新手，正在尝试调试脚本，该脚本有望允许用户使用Shift + Click选择表的多行并将复选框设置为selected。我在网上找到了一个示例，并尝试调试代码，但是我要在调用函数的行中排队，但是从未输入该函数。我不确定为什么吗？

这是脚本：

j$ = jQuery.noConflict();

j$(document).ready(function() {

    if(j$) {
        //alert('Jquery loaded successfully...');
    }
    console.log(j$('input[id$=btnSearch]'));
    j$('input[id$=btnSearch]').click(function(){
        console.log(j$('[id$=searchTable] > tbody tr'));
        var trs = j$('[id$=searchTable] > tbody tr');
        j$('tr').on('click', function(myEvent){
            //call the RowClick function on click event
            RowClick(j$(this),false,trs,myEvent)
        })
    });     
});

//declare variable to store the most recently clicked row
var lastSelectedRow;

// disable text selection
document.onselectstart = function() {
    return false;
}

function RowClick(currentrow, lock, rows, myEvent) {
    console.log('******************************************* we are inside the RowClick function');
    console.log(currentrow);
    console.log(lock);
    console.log(rows);
    console.log(myEvent);
    //if control is held down, toggle the row
    if (myEvent.ctrlKey) {
        toggleRow(currentrow);
    }

    //if there are no buttons held down...
    if (myEvent.button === 0) {

        //if neither control or shift are held down...
        if (!myEvent.ctrlKey && !myEvent.shiftKey) {
            //clear selection
            clearAll(rows);
            //toggle clicked row
            toggleRow(currentrow);
        }

        //if shift is held down...
        if (myEvent.shiftKey) {
            console.log('************************************** we are in the shift key branch');
            console.log(currentrow);
            console.log(currentrow.index());
            console.log(rows);
            console.log('************************************** we are calling the toggleRow function');
            toggleRow(currentrow);
            console.log('************************************** we have called the toggleRow function');
            //pass the indexes of the last selected row and currently selected row along with all rows
            selectRowsBetweenIndexes([lastSelectedRow.index(), currentrow.index()], rows)
        }
    }
}

function toggleRow(row) {
    console.log('******************************* we are inside the toggleRow function');
    console.log(row);
    if (!row.hasClass('header-row')){
        console.log('****************************** we are inside the row does not have the header-row class');
        lastSelectedRow = row.toggleClass('selected');
    }
}

function selectRowsBetweenIndexes(indexes,rows) {
    //sort the indexes in ascending order
    indexes.sort(function(a, b) {
        return a - b;
    });

    //for every row starting at the first index, until the second index...
    for (var i = indexes[0]; i <= indexes[1]; i++) {
        //select the row
        j$(rows[i+1]).addClass('selected');
    }
}

function clearAll(rows) {
    j$('.selected').removeClass('selected');
}

我到这一行：

console.log('************************************** we are calling the toggleRow function');

下一行输出是这一行：

console.log('************************************** we have called the toggleRow function');

从不输入toggleRow函数。我是jquery新手，不清楚我是否错误地调用了该函数？或者，为什么为什么看不到显示我已进入toggleRow函数的行的输出？

无法从另一个函数中调用一个函数
