for (int i = 0; i < toggles.Count; i++) { toggles[i].onValueChanged.AddListener(delegate (bool isOn) { if (isOn) { ShowHideOpenManager.instance.SingleSelect(gojs[i]); } else { } }); }

这段代码使用了一个循环来为Toggle列表中的每个Toggle添加值改变事件的监听器。
在每个Toggle的值改变事件监听器中,使用了一个匿名委托(delegate)来定义具体的操作。如果Toggle的值被设置为true(即被选中),则调用`ShowHideOpenManager.instance.SingleSelect()`方法,并传递相应的参数`gojs[i]`。否则,如果Toggle的值被设置为false(即取消选中),则不执行任何操作。
请确保在执行此代码之前,已经为`toggles`列表分配了正确的引用,并且`ShowHideOpenManager.instance`是一个有效的实例。同时,确保`ShowHideOpenManager.instance.SingleSelect()`方法已经正确实现。

<span @click="item.state == 1 && delData(item)" class="del-icon"><van-icon name="delete-o"/></span>
? item.state = 0 : item.state = 1">{{ item.state == 1 ? 'Active' : 'Inactive' }}</span>
This code creates a clickable span element that toggles between displaying "Active" and "Inactive" based on the value of the "state" property of the "item" object. When the span is clicked, the code checks if the "state" property is currently set to 1 (meaning active). If it is, it sets the "state" property to 0 (meaning inactive). If it isn't, it sets the "state" property to 1 (meaning active). The text displayed in the span is determined by whether the "state" property is currently set to 1 or 0.

To add a clock signal to this testbench, you can modify the code by declaring a clock signal as an input and using it to drive the testbench. Here's an example modification to the code:
```
module DW01_add_tb;
// Declare inputs and outputs
reg clk;
reg [3:0] A;
reg [3:0] B;
reg CI;
wire [3:0] SUM;
wire CO;
// Instantiate design under test
DW01_add dut(
.A(A),
.B(B),
.CI(CI),
.SUM(SUM),
.CO(CO)
);
// Initialize inputs
initial begin
A = 4'b0000;
B = 4'b0000;
CI = 0;
clk = 0;
end
// Add clock signal
always #5 clk = ~clk;
// Adder test case
task test_adder;
// Test case 1: 0 + 0 with carry-in of 0
A = 4'b0000;
B = 4'b0000;
CI = 0;
#10;
if (SUM !== 4'b0000 || CO !== 1'b0) $display("Test failed! 0 + 0 should be 0 with carry-out of 0");
// Test case 2: 7 + 3 with carry-in of 0
A = 4'b0111;
B = 4'b0011;
CI = 0;
#10;
if (SUM !== 4'b1010 || CO !== 1'b0) $display("Test failed! 7 + 3 should be 10 with carry-out of 0");
// Test case 3: 5 + 11 with carry-in of 1
A = 4'b0101;
B = 4'b1011;
CI = 1;
#10;
if (SUM !== 4'b0001 || CO !== 1'b1) $display("Test failed! 5 + 11 should be 16 with carry-out of 1");
// Test case 4: 15+15 with carry-in of 1
A = 4'b1111;
B = 4'b1111;
CI = 1;
#10;
if (SUM !== 4'b1110 || CO !== 1'b1) $display("Overflow!!!");
endtask
// Run test cases
initial begin
// Toggle clock signal
forever #5 clk = ~clk;
// Run test cases
test_adder();
$finish;
end
endmodule // DW01_add_tb
```
In this modified code, a clock signal `clk` is declared as an input and toggled every 5 time units using an `always` block. The test cases in the `test_adder` task can now be executed repeatedly using a `forever` loop that toggles the clock signal.
