如何完全删除文本框中的值存储？

Question

function NewRecord() {
   var id = Ext.getCmp('input_id').clear();
   var code = Ext.getCmp('input_code').clear();
   var description = Ext.getCmp('input_description').clear();
}

I need to remove the value from text box, it works but code behind still gets the id. The code above i do it in js.

Answer 1

Try this.

function NewRecord() {
       var id = Ext.getCmp('input_id').remove();
       var code = Ext.getCmp('input_code').remove()
       var description = Ext.getCmp('input_description').remove();
    }

Answer 2

Instead of using Id, you can set a value for the reference property. In view controller, call: this.lookupReference("refNameToTextBox") to get reference to the textbox;

Answer 3

function NewRecord() {
   var id = Ext.getCmp('input_id').setValue("");
   var code = Ext.getCmp('input_code').setValue("");
   var description = Ext.getCmp('input_description').setValue("");
}

you can clear the text value by setValue("") . please try this.
