javascript - 尝试在没有事件的情况下调用 jquery 函数

Question

因此将图像变成这样的链接

var imgCell = '<a href="javascript:storeInfo(&quot;text&quot;,&quot;text&quot;,&quot;ActiveProjects&quot;);"><img src="https://cubistmediagroup.sharepoint.com/sites/canvas/PublishingImages/details_open.png"></a>';

这会调用 storeInfo 函数，该函数将获取“text”、“text”和“activeprojects”并将它们设置为全局变量，以便多个 javascript 函数可以使用它们...

function storeInfo (filePath, webAddress, projectStatus){
theFilePath = filePath;
theWebAddress = webAddress;
controlButton(projectStatus);}

然后在 storeInfo 函数中我调用这个函数...

function controlButton (projectStatus){
$('#'+projectStatus+' tbody td img').live('click', function () {
    var theTable = ActiveProjectsTable;

    var nTr = this.parentNode.parentNode.parentNode;
    if ( this.src.match('details_close') )
        {
            // This row is already open - close it 
            this.src = "https://cubistmediagroup.sharepoint.com/sites/canvas/PublishingImages/details_open.png";
            theTable.fnClose( nTr );
        }
    else
        {
            // Open this row 
            this.src = "https://cubistmediagroup.sharepoint.com/sites/canvas/PublishingImages/details_close.png";
            theTable.fnOpen( nTr, fnFormatDetails(theTable, nTr), 'details' );
        }
});
}

因此，第一次单击 img 时，它会调用 store info 函数，而该函数又会调用 controlButton 函数...然后在控制按钮函数中，有一个需要再次单击的 jquery 代码函数...我想知道如果有一种方法可以在没有事件的情况下调用 jquery 函数，这样我就不需要两次点击。

调用 controlButton 后如何调用 jquery 函数？

Answer 1

function controlButton (projectStatus){
    // save the function into a variable
    var funct = function () {
        var theTable = ActiveProjectsTable;

        var nTr = this.parentNode.parentNode.parentNode;
        if ( this.src.match('details_close') )
        {
            // This row is already open - close it 
            this.src = "https://cubistmediagroup.sharepoint.com/sites/canvas/PublishingImages/details_open.png";
            theTable.fnClose( nTr );
        }
        else
        {
            // Open this row 
            this.src = "https://cubistmediagroup.sharepoint.com/sites/canvas/PublishingImages/details_close.png";
            theTable.fnOpen( nTr, fnFormatDetails(theTable, nTr), 'details' );
        }
    }
    // Retrieve the DOM node
    var node = $('#'+projectStatus+' tbody td img');

    // Apply the event listener to the node
    node.live('click', funct);

    // Call the function, with the retrieved node as the call instance('this')
    funct.call(node);
}
