If you want the table to have an editable function, you can embed the input tag in the tableThe function of {{list_one[1] or '}} is that when the value of list_one[1] is none, the front-end Web interface does not display none, but is displayed as emptyTableclass= "Table table-bordered"ID= "Parameters"> TR> thstyle= "width:5px">Variable nameth> th>Variable Valueth> TR>{% for list_one in info_list[8]%}TR>

Days using jquery to get the value of the Background-color in the style found that the color value in IE is not the same as the Chrome, Firefox display format, ie in the hex format display #ffff00, and Chrome, Firefox is in the GRB format to display RGB (255,0,0), because the need to store color values in the database, so you want to make the color value of the f

1 CString strInfo1; // Store the value selected in the drop-down list box 2 int NSel1; // the index that holds the drop-down list box selected 3 nSel1 = M_combox_first. GetCurSel (); // gets the index of the selected value 4 M_combox_first. Getlbtext (NSEL1,STRINFO1); // get the corresponding value by index 5 Setdlgitemtext (Idc_edit_city_info, m_strinfo); // set

For example, I'm going to jump to the B interface or the C interface from the A interface now.In that case, I need to write 2 intent. If you still want to involve the value of the intent, you will write two times to add the value of the method so if I use 1 bundle directly to save the value first and then save to the intent is not more concise? Another example i

Solution One:The maximum and minimum values in the array are evaluated separately. Scan through the array first to find the maximum number and the smallest number. Need to compare 2*n times.Solution Two:In general, the maximum and minimum values are not the same. So divide the array into two parts, and then find the maximum and minimum values from the two parts respectively.Finally, the max=9,min=3 are obtained from the odd and even digits, each need to compare N/2 times, the whole algorithm nee

To achieve the minimum value of the maximum value of the array, brute force method is much easier.
