当一个事件仍在进行中时，如何禁止用户多次单击操作列extjs

Question

我有一个操作列，我在某些情况下禁用它并有一个处理程序来进行ajax调用。但我想限制用户或拨打多个电话，直到一个电话完成。我不希望用户在单击时双击该图标。

ViewController方法：

    processDone: function (record) {
    //debugger;
    var me = this;
    var detailRecs = me.getStore('WarrantyDetail').data.items;
    if (!Ext.isEmpty(record) && (detailRecs.length > 0)) {
        canProcess = false;
        Ext.Array.forEach(detailRecs, function (r) {
            if (r.data.facilityId == 9 || r.data.amount == 0 || 
         Ext.isEmpty(record.data.qeContact)) {
                canProcess = true;

            }
        });
        if (canProcess) {
            Ext.Msg.alert('Invalid detail line item ');
            return;
        }        
        var detailLineAmt = me.getStore('WarrantyDetail').sum('amount');
        detailLineAmt = Math.abs(detailLineAmt);
        var headerAmount = Math.abs(record.data.amount)
       //if (me.getStore('WarrantyDetail').sum('amount') > 

     Math.abs(record.data.amount)){
            if (detailLineAmt > headerAmount){//added to check for range
               Ext.Msg.alert('Sum of Detail Amount must not be more than `
            Header Amount ');`
            return;
        }

        Ext.Ajax.request({
            url: webContext + 'url',
            success: function (response) {
                me.getStore('WarrantyHeader').reload();
            },
            failure: function (response) {
                me.getStore('WarrantyHeader').reload();
            }
        });
        this.getViewModel().set('currentHeader', null);
    } else if (!Ext.isEmpty(record) && (detailRecs.length == 0)) {
        Ext.Msg.alert('Please add atleast one detail lineItem');
    }
}

在操作列中为您的记录设置一个标志属性，并在您的ajax返回响应时将其设置回默认值。当您想要调用ajax时，请检查该标志属性。例如，在您的操作列处理程序中：

handler: function (tableview, rowIndex) {
       var rec = tableview.grid.getStore().getAt(rowIndex);
       if(!rec.ajaxFlag){
            //call your ajax here...
            rec.ajaxFlag = true;
       } 
}

在你的ajax中这样做：

Ext.Ajax.request({
        url: webContext + 'url',
        success: function (response) {
            record.ajaxFlag = false;//set flag to false
        },
        failure: function (response) {
            record.ajaxFlag = false;//set flag to false
        }
});
