Extjs optimization (2) Universal implementation of form submission_extjs

Copy code The code is as follows:

/**
* Submit form
*/
function $postForm( a) {
if (a.formPanel.getForm().isValid()) {
var b = a.scope ? a.scope: this;
a.formPanel.getForm().submit( {
scope: b,
url: a.url,
method: "post",
params: a.params,
waitMsg: "Submitting data...",
success: function(c, d) {
Ext.ux.Toast.msg("Operation information", "Successful information saved!");
if (a.callback) {
a. callback.call(b, c, d);
}
},
failure: function(c, d) {
Ext.MessageBox.show({
title: "Operation Message ",
msg: "Error saving information, please contact the administrator! ",
buttons: Ext.MessageBox.OK,
icon: "ext-mb-error"
});
if (a.callback) {
a.callback.call(b);
}
}
});
}
}

Using the modified code only requires 13 lines of code. The original requires 25-30 lines of code. Example:

Copy code The code is as follows:

saveRecord: function() {
$postForm({
formPanel:this.formPanel,
scope:this,
url: __ctxPath "/basedata/saveStudentDepartment.action ",
params:{},
callback: function(d, f) {
var e = Ext.getCmp("StudentDepartmentGrid");
if (e != null) {
e.getStore().reload();
}
b.close();
}
});
