Tera Term display chinese

admin — Thu, 29 Dec 2011 07:54:01 +0000

1) Change the “locale” to “cht”.

2) Change the “CodePage” to 950.

If the chinese word still cannot be display, you can try to change another font. It’s work for me.

jQuery – get element by id, class, name

admin — Thu, 15 Dec 2011 11:23:37 +0000

In jQuery, you can get elements with CSS class name and id easily.

For example,

1. ID: #id

$(‘#idA’) – selects all elements that have an id of ‘idA’, regardless of its tag name.
$(‘div#idA’) – selects all div elements that has an id of ‘idA’.

2. Class: .classname

$(‘.classA’) – selects all elements that have an class name of ‘classA’, regardless of its tag name.
$(‘div.classA’) – selects all div elements that has an class name of ‘classA’.

3. Class: [name="value"]

$(‘div[name^="nameA"]’) – selects all elements that have an name of ‘nameA’, regardless of its tag name.
e.g. [name*="value"], [name~="value"], [name$="value"]

3. Change attr: $(‘#idA’).attr()

$(‘#idA’).attr(‘src’, ‘value) – change value of attribute that have an idof ‘idA’, regardless of its tag name.
