10th Dec 2019How do I sort a table column of select->option html tags (by selected option)
Hi @allan and All,
I modified an example found in a forum to write custom filters (select option, textarea ..) idea is to write my regexp that will be used by search function to filter. It is working, but please let me know your thoughts (if it is good or it sucks :)
*_indexes variables (for example select_options_indexes) are indexes of columns depending on their type, and that I provide at beginning of script
// Apply the search
table.columns().every( function (index) {
// that is column
var that = this;
$( 'input', this.footer() ).on( 'keyup change clear search', function () {
that=table.columns(index);
// this is the input searched string typed in the column search field
if ( that.search() !== this.value ) {
column_search_string=this.value;
column_index=index;
if (input_indexes.includes(index)) {
if (this.value !== '') {
regex_expr='<input type="text".*value=".*'+this.value+'.*" maxlength=.*\>';
regex=true;
smart=false;
}
// when search text is cleared on input text column, there is no value attribute in the html input attrbute
// so regexpr will not match
else {
regex_expr='';
regex=false;
smart=false;
}
}
else if (select_options_indexes.includes(index)) {
regex_expr='[^]*selected="">[^<]*'+this.value+'.*</option>[^]*';
regex=true;
smart=false;
}
else if (text_area_indexes.includes(index)) {
regex_expr=this.value;
regex=false;
smart=true;
}
else if (simple_text_indexes.includes(index)) {
regex_expr=this.value;
regex=false;
smart=true;
}
search_col=that.search(regex_expr, regex, smart);
search_col.draw();
}
} );
} );
} );
thank you very much.
