Methods for multi-line query on ext list page_YUI.Ext related

First, there must be a tbar object

in Ext.grid.GridPanel and then add listeners: {
'render': function() {
bbar2.render(this.tbar); // add one tbar
//twoTbar.render(this.tbar); //add two tbar
// threeTbar.render(this.tbar); //add three tbar
}
}

You can see that there is bbar2 here so you can add a lot of bars

Copy the code The code is as follows:

this.bbar2 = new Ext.Toolbar({
renderTo: grid.tbar,
items:[]})

Of course There is a little trick. You can use "-" as the separator to represent

and it will be ok.
